#### Question

In a basket, the ratio between the number of oranges and the number of apples is 7: 13. If 8 oranges and 11 apples are eaten, the ratio between the number of oranges and the number of apples becomes 1: 2. Find the original number of oranges and the original number of apples in the basket.

#### Solution

Let the original number of oranges and apples be 7x and 13x.

According to the given information,

(7x - 8)/(13x - 11) = 1/2

14x - 16 = 13x - 11

x = 5

Thus the original number of oranges and apples are  7 x 5 = 35 and  13 x 5 = 65 respectively

Is there an error in this question or solution?
