Question

When I was 8 years old my brother’s age was half of my age. Then calculate the age of my brother when I was 80 years old.
1. 71 years
2. 56 years
3. 76 years
4. 87 years

Answer 1

Correct Answer - Option 3 : 76 years

Given:

I was 8 years and my brother’s age was half of my age.

Calculation

I was 8 years and my brother’s age half of my age.

My brother’s age = 8/2 = 4

The Age gap of my and my brothers = 8 – 4 = 4

Then my age = 80

My brothers age = 80 - 4 = 76 years

∴ When my age is 80 years at that time My brother’s age is 76 years
