Explanation
Ram will be 40 after 7 years, so he is currently 40-7=33 years old. y years ago, his age was 33-y. Option C (33-y) is correct.
A
Correct answer
Explanation
After 8 years, the son's age will be half of Ramu's current age (40/2 = 20). Therefore, the son's current age is 20 - 8 = 12 years. Option A is correct.
B
Correct answer
Explanation
Let son's age be x. Father's present age is x + 30. After 5 years: (x + 30) + 5 = 3(x + 5), so x + 35 = 3x + 15, giving x = 10. Father's present age = 10 + 30 = 40. Option A (30) would make father equal to son's age plus 30, not thrice after 5 years. C and D don't satisfy the condition.

D
Correct answer
Explanation
Let John's current age be x. Five years ago he was (x-5). In 8 years he will be (x+8). The equation is (x-5) = (x+8)/2. Solving: 2x-10 = x+8, so x = 18. Checking: five years ago he was 13, in 8 years he'll be 26, and 13 is half of 26.
D
Correct answer
Explanation
Let age be x. (x - 5) = 0.5 * (x + 8). Multiplying by 2: 2x - 10 = x + 8. Solving for x gives x = 18. Thus, John is currently 18 years old.
B
Correct answer
Explanation
Let Alice = x, Peter = x+5, John = 2(x+5). In 5 years: John+5 = 3(Alice+5) -> 2x+10+5 = 3x+15 -> 2x+15 = 3x+15 -> x=0. If Alice is 0, Peter is 5. John (10) will be 15, Alice (0) will be 5. 15 is 3x5.
