Correct Answer - Option 3 : Rs. 750
Given
Total Money = Rs 5625
Calculation
According to the question
Ratio of money, A : (B + C) = 1 : 2 ---(i)
Ratio of money, B : (A + C) = 1 : 4 ---(ii)
Equation (i) and (ii) multiply by 5 and 3 respectively
⇒ A : B + C = 5 : 10
⇒ B : A + C = 3 : 12
So, A : B : C = 5 : 3 : 7
Total Money = Rs 5625
⇒ 15x = 5625
⇒ x = 375
Required Answer = 5x - 3x
⇒ 2x = 2 × 375 = Rs 750
∴ The correct answer is Rs 750
