(A) Plant (B) Seed (C) Fruit (D) Seedling a) (D), (B), (C), (A) b) (B), (C), (A), (D) c) (D), (A), (C), (B) d) (C), (B), (D), (A) Answers & Solutions: 1) Answer (A) Present age of H =$117$years => R’s present age =$\frac{4}{13}\times117=36$years Thus, S’s present age =$\frac{2}{3}\times36=24$years Let after$x$years, the ages of R and S would be in the ratio =$15:11$=>$\frac{36+x}{24+x}=\frac{15}{11}$=>$396+11x=360+15x$=>$15x-11x=396-360$=>$x=\frac{36}{4}=9\therefore$After 9 years, the ages of R and S would be in the ratio of 15 : 11 => Ans – (A) 2) Answer (C) We have C = 3T = S/4 We have, C+S+T = 112 C +$\frac{C}{3}$+ 4C = 112$\frac{16C}{3} = 112$C = 21 years So age of S = 21 * 4 = 84 years Hence, option C is the right answer. 3) Answer (C) A is 4 years older than B, B is thrice as old as C,the sum of ages of A,B,C is 11 A=B+4 ——- (1) B=3C ——- (2) A+B+C=11 ——- (3) Equation (3) can be written as, B+4+B+(B/3) = 11 2B + 4 + (B/3) = 11 6B + 12 + B = 33 7B + 12 = 33 B = 3. Hence, the age of B after 6 years is 9 years. 4) Answer (B) Let the present age of Aman be x and the present age of Agam be y. So we know that$\frac{x – 7}{y – 7} = \frac{3}{4}$=> 4x – 28 = 3y – 21 => 4x – 3y = 7 We have also been given that$\frac{x + 17}{y + 17} = \frac{7}{8}$=> 8x + 136 = 7y + 119 => 8x – 7y = -17 Solving the two equations, we get y = 31 and x = 25 Thus, the sum of their present ages is 56 Hence, 5 years from now, the sum of their ages will be 56 + 10 = 66 years 5) Answer (B) The below diagram can be drawn using given statements. Shortest distance between his home and point B$= \sqrt{28^2 + 45^2} = \sqrt{784+2025} = \sqrt{2809} = 53$metres 6) Answer (D) The below diagram can be drawn using given statements. Here, His office is in North-East direction with respect to his home. 7) Answer (A) The below diagram can be drawn using given statements. Shortest distance between his home and his office$= \sqrt{48^2 + 55^2} = \sqrt{2304+3025} = \sqrt{5329} = 73$metres 8) Answer (C) Number – 846721 None of the conditions are applied, the codes are written as given. Thus, 846721 : !&%+*x => Ans – (C) 9) Answer (B) Number – 25486 The number ends by an even number, thus condition (ii) is applied and the even number is coded as = © Thus, 25486 : *$&!©

=> Ans – (B)

The following coding pattern has been used above :

(i) If two different vowels are there between two different consonants, then each vowel is coded as [15] and the code for each consonant is [5].
(ii) If there is only one vowel between two different consonants, then the vowel is coded as [10].
(iii) If there is one consonant between two vowels, the code for each vowel is [0].
(iv) If there are two similar vowels between two different consonants, then the code for each vowel is [20].
(v) If there are two vowels at the second and the last positions respectively, then each vowel is coded as [25].
(vi) If there are two different vowels at the first and third positions respectively, and there are two different consonants at the second and the last positions respectively. then the code for each vowel is [30].
(vii) The code for each consonant is [5].

Applying rules (vi) and (vii), we can conclude that if there are two vowels at first and third positions, and two consonants at second and fourth positions, then

the code will be [30] [5] [30] [5]

Clearly, ARID & EVIL follow this pattern.

(vi) If there are two different vowels at the first and third positions respectively, and there are two different consonants at the second and the last positions respectively. then the code for each vowel is [30].
(vii) The code for each consonant is [5].

Applying rules (iii) and (vii), we can conclude that there should be a consonant between two vowels for it to be coded as [0].

This pattern is followed by ARE & ORE.

Marrow is inside the bone, flesh covers bone, skin covers flesh and nails are above the skin.
Hence, option D is the right answer.

The order from lower to higher is Clerk -> Secretary -> Director -> Governor -> President
Hence, option B is the right answer.

Room is in the house, house in the neighbourhood, neighbourhood in city and city in state. Hence, 53124 is the correct order.

$\equiv$ (D), (A), (C), (B)
