Answer 2

Answer:

The increase is 40%.  

Step-by-step explanation:

Given : Increase ₹250 in the ratio 7:5.

To find : What is the increase?

Solution :

Let us consider x be the number,

According to question,

$x : 250 = 7:5$

$\frac{x}{250} =\frac{7}{5}$

Cross multiply,

$5x=250\times 7$

$5x=1750$

$x=\frac{1750}{5}$

$x=350$

Increase in amount is x-250=350-250=100.

Converting into percentage,

$\frac{100}{250}\times 100=40\%$

Therefore, The increase is 40%.
