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

(x)/(250) = (7)/(5)  

Cross multiply,

5x = 250 x 7

5x = 1750

x = (1750)/(5)

x = 350  

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

Converting into percentage,

(100)/(200) x 100 = 40%

Therefore, The increase is 40%.
