Answer 1

ratio of cost of one mango to cost of apples=2/5
15x+7y=10x+9y
5x=2y
x/y=2/5

Answer 2

Answer:

Ratio of cost of one mango to cost of apples $=\frac{2}{5}$

Step-by-step explanation:

Given : 15-mangoes and 7-apples cost as much as 10-mangoes and 9-apples.

To find : What is the ratio of cost of one mango to cost of one apple?

Let cost of mangoes = x

Let cost of apples = y

15-mangoes and 7-apples cost = $15x+7y$

10-mangoes and 9-apples cost = $10x+9y$

We have given that 15-mangoes and 7-apples cost as much as 10-mangoes and 9-apples.

$15x+7y=10x+9y$

$5x=2y$

$\frac{x}{y}=\frac{2}{5}$

Therefore, ratio of cost of one mango to cost of apples $=\frac{2}{5}$
