Son's age in 3 years is 15, so current age is 12. Man is 4 times as old as son, so man is 4 * 12 = 48. Man is 3 years older than wife, so wife is 48 - 3 = 45.

C Correct answer
Explanation

Let son's age be x. Father's age is 5x + 1. After 3 years, father is 5x + 4 and son is x + 3. The equation is 5x + 4 = 4(x + 3) - 2. Solving gives 5x + 4 = 4x + 12 - 2, so x = 6. Father's age is 5(6) + 1 = 31.

Multiple choice

The age of a father is twice that of his son’s at present age. After 5 years the sum of their ages will be 85. How old are they now? पिता की आयु अपने पुत्र की वर्तमान आय से दोगुनी है। 5 वर्ष बाद उनकी आयु का योग 85 होगा तो अब उनकी आयु क्या होगी ?

  1. 40, 20

  2. 26, 76

D Correct answer
Explanation

F = 2S. (F+5) + (S+5) = 85. F + S + 10 = 85, F + S = 75. 2S + S = 75, 3S = 75, S = 25, F = 50.

B Correct answer
Explanation

Let M and S be current ages. Two years ago: M-2 = 4(S-2) => M = 4S - 6. Six years from now: M+6 = 2(S+6) + 10 => M = 2S + 16. Equating: 4S - 6 = 2S + 16 => 2S = 22 => S = 11. Then M = 4(11) - 6 = 38. Ratio M:S = 38:11.

Multiple choice

B Correct answer
Explanation

Let Nidhi's present age be n. The condition eight years from now gives Sakshi's age as 3n + 16, and n(3n + 16) = 320. The positive solution is n = 8 and Sakshi is 40 now, so her age when Nidhi was born was 40 - 8 = 32 years.
