Correct Answer - Option 1 : Rs. 456
Given:
Ratio of share of A, B and C = 3 ∶ 7 ∶ 5
Total profit = Rs. 6840
Calculation:
Let the share of A, B and C = 3a, 7a and 5a
The sum of money = Rs. 6840
3a + 7a + 5a = Rs. 6840
⇒ 15a = Rs. 6840
⇒ a = 6840/15
⇒ a = Rs. 456
Money A and C earned more than B = (3a + 5a) - 7a
⇒ 8a - 7a
⇒ a = Rs. 456
