Question

Anuj was 137 cm tall when he was 8 years old. Now his height is 158 cm. His increase in height is ________.

1. 17
2. 23
3. 20
4. 21

Answer 1

Correct Answer - Option 4 : 21

Anuj’s height at age of 8 → 137 cm

Present height of Anuj → 158 cm

Increase in height = Present height – Height at the age of 8

= 158 – 137

= 21 cm

Therefore, the increase in height of Anuj is 21 cm.

Hence, ‘21 cm’ is the correct answer.
