In the initial years, trade policy in our country was primarily aimed at regulating imports having regard to the nascent stage of country’s development and the need to encourage domestic production through import substitution measures. However, with the onset of liberalisation the importance of globalisation through trade and making exports the engine of growth of economy has been recognised. Export promotion is now a continuous and sustained effort and specific steps in this direction have been taken and achievements have been made in recent years.
Question 15: Import used to affect domestic production in earlier years.
a) if inference is “definitely true”, i.e., it properly follows from the statement of facts given.
b) if the inference is “probably true” though not “definitely true” in the light of the facts given.
c) if the “Data are inadequate”, i.e., from the facts given you cannot say whether the inference is likely to be true or false.
d) if the inference is “probably false” though not “definitely false” in the light of the facts given.

Answers & Solutions:
1) Answer (C)
The logic followed here is (n + 9). Hence, the code for GAFT will be,
G + 9 = P, A + 9 =J, F + 9 = O, T + 9 = C.
Similarly, the code for WORS is,
W + 9 = F, O + 9 = X, R + 9 = A, S + 9 = B.
Hence, option C is the correct answer.
2) Answer (C)
$84 = 8^2 – 4^2 = 64 – 16 = 48$
Using the same logic,
$73 = 7^2 – 3^2 = 49 – 9 = 40$.
Therefore, option C is the right answer.
3) Answer (B)
There are 6 members, 3 generations and 2 married couples. There are 2 married couples and there are 2 members in each generation. Deepthi is married to the engineer and Deepthi’s mother is Bhanu. Therefore, the family structure must be as shown below.
Deepthi must belong to the second generation and Bhanu must belong to the first generation. Lawyer is teacher’s son and Doctor is the husband of teacher’s mother. Therefore, Deepthi must be the teacher and Bhanu must be Deepthi’s mother.
The singer is the grandmother of the CA. Therefore, Bhanu must be the singer. Farukh is the son-in-law of the doctor and likes blue colour. Therefore, Farukh must be the engineer and Deepthi’s husband. Deepthi is related to Chirag the same way Aruna is related to Farukh. Aruna must be the daughter of Farukh and hence, Chirag must be the father of Deepthi.
Aruna is not a lawyer by profession. Therefore, Aruna must be the CA and Eswar must be the lawyer.
Farukh likes blue colour. The CA, lawyer, doctor and the singer do not like green colour. Therefore, Deepthi must like green colour. The doctor and his spouse do not like pink colour. Aruna’s brother likes orange. Therefore, Aruna must like pink colour.
Deepthi’s father likes red colour. Therefore, Deepthi’s mother must like yellow colour.
The final arrangement is as follows:
Lawyer is the grandson of the person who likes yellow colour. Therefore, option B is the right answer.
4) Answer (D)
There are 6 members, 3 generations and 2 married couples. There are 2 married couples and there are 2 members in each generation. Deepthi is married to the engineer and Deepthi’s mother is Bhanu. Therefore, the family structure must be as shown below.
Deepthi must belong to the second generation and Bhanu must belong to the first generation. Lawyer is teacher’s son and Doctor is the husband of teacher’s mother. Therefore, Deepthi must be the teacher and Bhanu must be Deepthi’s mother.
The singer is the grandmother of the CA. Therefore, Bhanu must be the singer. Farukh is the son-in-law of the doctor and likes blue colour. Therefore, Farukh must be the engineer and Deepthi’s husband. Deepthi is related to Chirag the same way Aruna is related to Farukh. Aruna must be the daughter of Farukh and hence, Chirag must be the father of Deepthi.
Aruna is not a lawyer by profession. Therefore, Aruna must be the CA and Eswar must be the lawyer.
Farukh likes blue colour. The CA, lawyer, doctor and the singer do not like green colour. Therefore, Deepthi must like green colour. The doctor and his spouse do not like pink colour. Aruna’s brother likes orange. Therefore, Aruna must like pink colour.
Deepthi’s father likes red colour. Therefore, Deepthi’s mother must like yellow colour.
The final arrangement is as follows:
Bhanu is married to the person who likes red colour. Therefore, option D is the right answer.
5) Answer (A)
O sits second to the right of J. Here there are two possibilities. If O faces inside, then the persons to his right and left face outside and so on. If O faces outside, then the persons to his right and left faces inside and so on. The husband of O sits to the immediate right of the person who is opposite to O.
P is the father of K and they both sit opposite to each other. P is not an immediate neighbour of O. Assuming P is the wife of O in Possibilities I and II.
N sits second to the right of his mother-in-law. Hence, N should have a wife and his mother-in-law should have a husband. There is only one son of K. Hence, Three generations are K’s generation, K’s father(P)’s generation and K’s son’s generation.
M is the nephew of Q and they are immediate neighbours of each other. Q is unmarried and O has only two children. Hence, P is husband of O and N is husband of K. Then, Possibilities III and IV can be eliminated.
N sits second to the right of his mother-in-law. O is his mother-in-law.
J sits opposite to her brother-in-law. Hence, N is J’s brother-in-law. Then, K is N’s wife.
L is an immediate neighbour of her grandmother.
L and M are siblings and they both face opposite directions.
In Possibility-I, Since L is facing inside, M faces outside.
In Possibility-II, Since L is facing outside, M faces inside.
M and Q are immediate neighbours.
The person who is third to the right of K faces inside. Hence, Possibility-I can be eliminated.
Therefore, Final arrangement is as shown above.
K is sister of J. P sits opposite to K.
6) Answer (C)
O sits second to the right of J. Here there are two possibilities. If O faces inside, then the persons to his right and left face outside and so on. If O faces outside, then the persons to his right and left faces inside and so on. The husband of O sits to the immediate right of the person who is opposite to O.
P is the father of K and they both sit opposite to each other. P is not an immediate neighbour of O. Assuming P is the wife of O in Possibilities I and II.
N sits second to the right of his mother-in-law. Hence, N should have a wife and his mother-in-law should have a husband. There is only one son of K. Hence, Three generations are K’s generation, K’s father(P)’s generation and K’s son’s generation.
M is the nephew of Q and they are immediate neighbours of each other. Q is unmarried and O has only two children. Hence, P is husband of O and N is husband of K. Then, Possibilities III and IV can be eliminated.
N sits second to the right of his mother-in-law. O is his mother-in-law.
J sits opposite to her brother-in-law. Hence, N is J’s brother-in-law. Then, K is N’s wife.
L is an immediate neighbour of her grandmother.
L and M are siblings and they both face opposite directions.
In Possibility-I, Since L is facing inside, M faces outside.
In Possibility-II, Since L is facing outside, M faces inside.
M and Q are immediate neighbours.
The person who is third to the right of K faces inside. Hence, Possibility-I can be eliminated.
Therefore, Final arrangement is as shown above.
L is granddaughter of O. M is third to the right of O.
7) Answer (C)
The given statements can be combined and expressed as $ C = A > B < D \leq E = F$.
$F \leq C$ can be written as $ A \geq E$.
The 2 conclusions, state that $ A < E $ or $ A \geq C$.
One among these 2 conclusions must definitely follow.
Therefore, either conclusion I or conclusion II follows. Therefore, option C is the right answer.
8) Answer (E)
The given statements can be combined as $R = S < T > Q \geq P$.
$T$ is greater than $Q$. Therefore, $T$ is definitely greater than $P$. Conclusion I is false since it states that $T \geq P$.
No relationship can be established between $R$ and $Q$ since there is a change in the sign of the inequality. Therefore, conclusion II does not follow.
Neither of the conclusions follow. Therefore, option E is the right answer.
9) Answer (B)
18 can be written as 16+0+0+2+0 = $\blacktriangle\circ\circ\blacktriangle\circ$
10) Answer (D)
$\blacktriangle \blacktriangle\blacktriangle\circ$ = 8+4+2+0 = 14
11) Answer (D)
The logic can be explained as follows.
First, it is checked whether the input is less than 0. If it is not, then we increment ‘n’ by 3 and recheck whether the given number is less than or equal to ‘n’. The process is repeated till ‘n’ becomes equal to or greater than the input.
Finally, the input is subtracted from ‘n’. Thus, we get the number that must be added to make the given number divisible by 3.
Hence, option D is the right answer.
12) Answer (E)
The logic can be explained as follows.
First, it is checked whether the input is less than 0. If it is not, then we increment ‘n’ by 3 and recheck whether the given number is less than or equal to ‘n’. The process is repeated till ‘n’ becomes equal to or greater than the input.
Finally, the input is subtracted from ‘n’. Thus, we get the number that must be added to make the given number divisible by 3.
So, when k=5, n=6. If n+k is displayed as the output, then 5+6 = 11 will be the output.
13) Answer (A)
From I, B is younger only to one person. B’s age is the average of C and D. D is the eldest as C is neither the youngest nor the eldest.
II – There are as many people as old as E as there are younger to him. The age of B is twice that of E.
Nothing can be concluded from II.
14) Answer (B)
From II,
We can conclude that only such possibility is that R lives on 5 and T on 3.
Thus, option B is the correct answer.
15) Answer (A)
The inference is repetition of the phrase : encourage domestic production through import substitution measures.
Thus, the inference is “definitely true”.
=> Ans – (A)
16) Answer (A)
The word ‘regulating imports’ makes the inference that before the implementation of the idea of liberalisation, the trade policy was not much in favour of free import-export definitely true
Thus, the inference is “definitely true”.
=> Ans – (A)
17) Answer (B)
Given all the lanes are running from south to north so they are facing north.
Given N and L are separated by 7 km and also Q and P are separated by 7 km but P and Q are not adjacent to each other since they have 1 lane between them so N and L are adjacent lanes separated by a distance of 7km.
O is the 4th lane from any side as it is mentioned as middle most lane. M is the 1st lane from left as given in the question. Given L and Q are separated by only 1 lane so by using the above conditions we have the below cases as shown in the figure
From the above four possibilities 4 and 2 are not possible because R is to the right of Q but no slot is empty towards the right of Q and distance between the lanes O and Q is 3 km and in possibility 2 we have more than 3 km between them and so possible cases are 1 and 3
Distance between Q and P is 7 km and so in possibility case 3 we can slot P in 2nd from left but adjacent lanes having 7km are N and l and so not possible and the other place is first from right but if we slot P in that place distance between Q and P will not be 7 and it will be greater than 7 and so possibility case 3 is not possible only case possible is 1 and so the required arrangement is shown in the below figure
Since distance between QP is 7km QR and RP should be 2km and 5km or 5km and 2km.
Distance between the lanes M and O is 4+7+1=12 km
18) Answer (B)
Given all the lanes are running from south to north so they are facing north.
Given N and L are separated by 7 km and also Q and P are separated by 7 km but P and Q are not adjacent to each other since they have 1 lane between them so N and L are adjacent lanes separated by a distance of 7km.
O is the 4th lane from any side as it is mentioned as middle most lane. M is the 1st lane from left as given in the question. Given L and Q are separated by only 1 lane so by using the above conditions we have the below cases as shown in the figure
From the above four possibilities 4 and 2 are not possible because R is to the right of Q but no slot is empty towards the right of Q and distance between the lanes O and Q is 3 km and in possibility 2 we have more than 3 km between them and so possible cases are 1 and 3
Distance between Q and P is 7 km and so in possibility case 3 we can slot P in 2nd from left but adjacent lanes having 7km are N and l and so not possible and the other place is first from right but if we slot P in that place distance between Q and P will not be 7 and it will be greater than 7 and so possibility case 3 is not possible only case possible is 1 and so the required arrangement is shown in the below figure
Since distance between QP is 7km QR and RP should be 2km and 5km or 5km and 2km.
So the required answer is 4th to the left
19) Answer (D)
1st, 3rd, 8th and 10th letters of the word ASSIGNMENT are A, S, E, T.
SEAT, EAST and EATS can be formed using A, S, E, T.
Hence, Option D is the correct answer.
20) Answer (D)
3rd, 5th, 8th and 9th letters of the word PERCENTAGE are R, E, A, G.
GEAR and RAGE can be formed using R, E, A, G.
Hence, Option D is the correct answer.
