Best answer
Correct Answer - Option 2 : 3120

Given: 

The amount = 9620 rupees, 

A : C = 2 : 3, and B : C = 4 : 5

Calculation: 

A C B
2 3  
  5 4

Now, We make C equal in both part
A C B
2 × 5 = 10 3 × 5 = 15  
  5 × 3 = 15 4 × 3 = 12


The ratio becomes A : C : B is 

⇒ 10 ∶ 15 ∶ 12

So, The share's B is 

⇒ [12/(10 + 15 + 12)] × 9620

⇒ (12/37) × 9620

⇒ 12 × 260

⇒ 3120 rupees

∴ The share's of B is 3120 rupees.
