Question

a man sold a fridge for Rupees 6251 and lost 1 by 20 of the cost price find the cost price

Answer 1

SP of the fridge=Rs 6251
Let the CP be x
Loss=1/20 of CP

LOSS=CP-SP
1/20x=x-6251
1/20x-x=-6251
-19x/20=-6251
On solving x =6580

CP= Rs 6580

Answer 2

Heya

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.
