Correct Answer: B
Let total students be N. Total marks = 39N. 39N - (5+12+15+19) = 44(N - 4) → 39N - 51 = 44N - 176 → 5N = 125 → N = 25.
Q5893.A father is 7 times as old as his son. Two years ago, he was 13 times as old. What are their current ages?
Correct Answer: B
Let the son's age be s, so the father's age is 7s. Two years ago: 7s - 2 = 13(s - 2) => 7s - 2 = 13s - 26 => 6s = 24 => s = 4. The father is 7 * 4 = 28 years old.
Q5894.A father was twice the age of her daughter 4 years ago. The sum of their ages is 47. What is the daughter's age today?
Correct Answer: D
Let the daughter's current age be d, so the father's current age is 47 - d. Four years ago: daughter was d - 4 and father was (47 - d) - 4 = 43 - d. Equation: 43 - d = 2(d - 4) => 43 - d = 2d - 8 => 3d = 51 => d = 17.
