A mother gives pocket money to her three children A, B and C in the ratio 3 : 4 : 5 respectively. Then the father gives ₹ 40 to each child. As a result, the pocket money of A, B and C now has the ratio 5 : 6:7 respectively. How much does C get from her mother ?

Result

Your answer: — · Correct: B

Explanation

Let the initial amounts of pocket money given by the mother to A, B, and C be 3x, 4x, and 5x respectively. After the father gives ₹ 40 to each child, the new amounts are (3x + 40), (4x + 40), and (5x + 40).

The new ratio is given as 5 : 6 : 7. We can set up an equation using the shares of A and B:

(3x + 40) / (4x + 40
