Answers & Solutions:

1) Answer (B)

Let the total number of children be N.

Number of sweets received by each child = N/5

So, N * N/5 = 605 => $N^2 = 605 * 5$ = 3025

So, N = 55

Number of sweets received by each child = 55/5 = 11

2) Answer (B)

Let the average of the six batsmen be x.

So, runs scored by the captain = x+30

Total score of the team = 6x + x + 30 = 7x + 30 = 310 => x = 40

So, the score of the captain = 70

3) Answer (C)

One eighth of the amount received by each son is equal to one tenth the amount received by each daughter.

As each daughter received Rs. 1.25 lakhs, it means that each son received 1.25*8/10 = 1 lakh.
So, the total amount received by 3 sons and 2 daughters is 3*1 + 2*1.25 = 5.5 lakhs

Hence, the amount received by the wife is 40%*5.5 = 2.2 lakhs

Amount received by each grandson is 1/10th the amount received by each daughter i.e 0.125 lakhs
Hence, the total amount received by 5 grandchildren is 5*0.125 = 0.625 lakhs

So, total received by wife and grandchildren is 2.2 + 0.625 = 2.825 lakhs = 2,82,500

4) Answer (B)

A+B+C+D = 40*4 = 160

A+B+E+F = 40*4 = 160

So, A+B = 160 – C – D = 160 – E – F

So, C + D = E + F

Option b) is the correct answer.

5) Answer (E)

Consider the following set: {2, 4, 6}

The mean of the set is 4 and so is the median. From this, we can rule out options a), c) and d).

Consider another set: {1, 3, 5}. Here also, mean = median = 3

This case rules out option b).

So, option e) is the correct answer.

6) Answer (C)

The value of two-fifth of 200 is 2/5*200 = 80
The value of three-fifth of 125 is 3/5*125 = 75

Hence, their difference is 80-75 = 5

7) Answer (D)

Let the number be equal to XY.
Hence, it’s value equals 10X+Y
And the value of the number obtained by reversing the digits is 10Y+X

Their difference equals 9Y-9X which equals 27
Or, Y-X = 3

We also know that Y=2X. Hence, X=3 and Y=6

Therefore the original number is 36 and half of it equals 18

8) Answer (C)

The salary of the employee today is Rs. 10000
The salary of the employee after one year is 10000*1.5 = Rs. 15000
The salary of the employee after two years is 15000*1.5 = Rs.22500
The salary of the employee after three years is 22500*1.5 = Rs. 33750
The salary of the employee after four years is 33750*1.5 = Rs. 50625

9) Answer (C)

Let the four consecutive odd numbers be a, a+2, a+4 and a+6.
So, their sum is 4a+12 = 96
Or a = 21
So, the four odd numbers are 21,23,25 and 27
So, the required product is 23*27 = 621

10) Answer (B)

The total of the given set of numbers equals 125+236+334+486+564+625+702+800 = 3872
As they are eight numbers, their average becomes 3872/8 = 484

Answer is option B

11) Answer (A)

Let the number be X.
So, 55%*X – 14%*X = 8610
Therefore, 41%*X = 8610
Or X = 8610 * 100/41 = 21000

Therefore, 85% of the number is 85%*21000 = 17,850

12) Answer (A)

Let the current ages of Palash and Arnav be P and A respectively.

So, P = 3A
After 7 years, Palash will be twice Arnav’s age. So, P+7 = 2(A+7)
So, 3A + 7 = 2A + 14 or A = 7
Hence, P = 21 years

Arnav’s age after fourteen years is 7+14 = 21
Hence, the required ratio is 21:21 = 1

13) Answer (A)

The total marks obtained by Paresh is 102+118+104+114+96 = 534
The total marks that could have been obtained is 120*5 = 600

So, the overall percentage obtained by Paresh is 534/600 * 100 = 89%

14) Answer (C)

The marks the students gets is 520.
As the students failed by 5%, percentage of marks received by the student is 55-5 = 50%

Hence, the maximum aggregate marks that a student could have received is 520*100/50 = 1040

15) Answer (A)

The average height of the four girls is 150 cm.
Hence, the total height of the four girls is 150*4 = 600 cm.

The average height of three of the four girls is 148 cm.
Their total height is 148*3 = 444 cm

Hence, the height of the fourth girl is 600-444 = 156 cm

16) Answer (E)

The value of three-fifth of 350 is $\frac{3}{5}*350 = 210$
The value of four-seventh of 210 is $\frac{4}{7}*210 = 120$

Hence, the difference is $210-120 = 90$

17) Answer (C)

The list of given numbers is 132,148,164,128,120,136
Their total equals 132+148+164+128+120+136 = 828

As there are six numbers, their average equals 828/6 = 138

18) Answer (E)

Let the number be X.
As 56% of the number is less than its 72% by 56, it implies that (72% – 56%)*X = 56
Or, 16% of X = 56.
Therefore, X = 56*100/16 = 350

Therefore, 70% of the number is 350*70% =255.
As this is not among any of the options given, the correct answer is option (e)

19) Answer (C)

Let the five numbers be a, a+2, a+4, a+6 and a+8

So, a+(a+2)+(a+4)+(a+6)+(a+8) = 380
Therefore, 5a + 20 = 380
Or a = 72

Hence, the second number in ascending order is a+2 = 74

20) Answer (B)

The percentage of money Nandkishore gave to his wife and sons equals 35% + 50% = 85%
So, percentage of money remaining is 100% – 85% = 15%

This equals 11,250.
Hence, the total amount Nandkishore had is 11250 * 100/15 = Rs. 75,000
