Question

A man sold a fridge for rs.6251 and lost 1÷20 of the cost pries . find the cost pries

Answer 1

Selling price = 6251

Cost price = x

cost price - selling price  = 1/20 of cost price

x - 6251 = 1/20 x

x - 6251 = x/20

20(x- 6251) = x

20x - 125020 = x

20x - x = 125020

19x = 125020

x = 6580

⇒ Cost price of the fridge is Rs. 6580.

Answer 2

let c.p=x
loss= x/20
s.p=cp-loss
6251=x-x/20
6251=19x/20
19x=6251×20
$x = 6251 \times 20 \div 19 \\ 329 \times 20 \\ 6580$
