Answer 2

Answer:

Brother's age will be 16 years.

Explanation:

Given,

Brother's age will be half when I was 4 years,

Let my age be x and Brother's age will be y

when, x = 4, y will be

y = 4/2 = 2 years

Thus, the difference between me and my brother's age will be

x - y = 4 - 2 = 2 years.

So, when I was 18, my brother's age will be

x - 2 = 18-2 = 16 years.

Thus, my brother's age will be 16 years.
