Brian is 8 and his brother is twice his age. How old will his brother be when Brian is 11?

Solution:

Age of Brian = 8

His brother is twice his age = 8 × 2 = 16

When Brian’s age = 11, it is 3 added to his present age.

Age of his brother when Brian is 11 = 16 + 3 = 19

Therefore, when Brian's age is 11 his brother is 19 years old.

Brian is 8 and his brother is twice his age. How old will his brother be when Brian is 11?

Summary:

Brian is 8 and his brother is twice his age. When Brian is 11 his brother will be 19 years old.
