C Correct answer
Explanation

Let Ram's present age be R and son's be S. 20 years ago, R-20 = 5(S-20). The son will be 41 in 16 years, so S+16 = 41, meaning S = 25. Substituting S=25 into the first equation: R-20 = 5(25-20) = 25, so R = 45.

AI explanation

The son will be 41 years old in 16 years, so his present age is 41 minus 16, which is 25 years. Twenty years ago, the son's age was 25 minus 20, which is 5 years. At that time, Ram was five times as old as his son, making Ram's age 5 times 5, equaling 25 years. Therefore, the present age of Ram is 25 plus 20, which is 45 years.
