Riddle

Peter is 4 and his little brother is 2, half his age. How older will Peter's little brother be when he is 100?

Choose an answer

A.96
B.50
C.100
D.98 because there's only a 2-year difference.
Hint: It's a 6-word phrase with 32 letters, starting with "9".

Answer

98 because there's only a 2-year difference.

Why this is the answer

The 2-year age gap between the brothers stays constant regardless of their ages, so when Peter turns 100, his brother turns 98.
