Question

A loss of 18 percent gets converted into a profits of 15 percent when the selling price is increased by Rs. 198. The cost price of the aricle is.

Answer 1

Let the Cost Price be Rs a

Original Selling price = CP - Loss

= a - 18 % of a

= a - 18a/100

= 82a/100

= 41a/50

New Selling price = 41a/50 + 198

Now,

New Selling price = Cost Price + 15 % of cost Price

=> 41a/50 + 198 = a + 15 % of a

=> 41a / 50 + 198 = a + 15a/100

=> 41a/50 + 198 = 115a/100

=> 198 = 115a/100 - 41a/50

=> 198 = ( 115a - 82a) / 100

=> 198 = 33a / 100

=> a = 198 × 100 / 33

=> a = 600

Cost Price = Rs 600
