Best answer
Correct Answer - Option 4 : 30

Given:

Number of chocolates Rahul, Rohan and Radhika have x, x/3 and 2x -10 respectively

Total number of chocolates = 90

Concept:

Simple addition

Calculation:

⇒ x + x/3 + 2x - 10 = 90

⇒ 3x + x + 6x = 100 × 3

⇒ 10x = 300

⇒ x = 30

∴  Rahul has 30 chocolates.
