The difference between the ages of P and Q was 19 years when Q was 53. C is elder to Q by 4 years. What will be the age difference between P and C when C becomes 60?

Correct option is B

The age of Q = 53

As C is elder to Q by 4 years,

So, the age of C = 57

If P is younger than Q, then age of P = 34

And if P is older than Q, then age of P = 72

when the age of C is 60 years, the age of P will be 37 years, and the difference between the age of P and C will be 23 years. Another possibility is eliminated as (75 - 60) = 15 is not present in the options.

Hence, the correct answer is "23 years".
