B Correct answer
Explanation

Leo = Rameem + 7. Leo/Rameem = 10/3. (Rameem + 7)/Rameem = 10/3. 3R + 21 = 10R. 7R = 21. R = 3. Leo = 10.

AI explanation

Let Rameem's present age be 3x years and Leo's present age be 10x years. The age difference is given by 10x - 3x = 7, which simplifies to 7x = 7 and yields x = 1. Therefore, Rameem is 3 years old and Leo is 10 years old.
