Question

1. 300
2. 100
3. 150
4. 50

Answer 1

Correct Answer - Option 3 : 150

Given:

Kishan’s height = 240 cm

Ram’s height = 1/4 × Kishan’s height

Concept:

Average height = Total height/Total persons

Solution:

Kishan’s height = 240 cm

Ram’s height = (1/4) × Kishan’s height

⇒ (1/4) × 240 = 60 cm

Average height = (240 + 60)/2

⇒ 300/2 = 150 cm
