Question

if the price of an article is increased by 25% the increase is rupees 10 find the new price

Answer 1

let x be the cost of an article

25%of x = 10

1/4x = 10
x = 40


so the new prise = 40+10

50

Answer 2

Let the cost price be x.

The increase is 25%.

the new price is :

1.25x

The increase is 0.25x

Now :

0.25x = 10

x = 10/0.25 = 40

The new price is thus :

1.25 × 40 = 50

= rupees 50
