Correct Answer  Option 2 : 3120
Given:
The amount = 9620 rupees,
A : C = 2 : 3, and B : C = 4 : 5
Calculation:
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.
