Question

A man sold a taperecorder at a gain of 8% .The gain would have been 10% , if the tape recorder had been sold for 35 Rs more. Find the cost price of taperecorder.

Answer 1

Selling price is 35rs

New profit 10% is 3.5 rs

Old profit is 8 % from 10 %

So the cost price is 30.87 rs

Answer 2

Answer:

Answer : 1750

Solution :

let cp=x

10% of x = 8% of x + 35

(1/10)x = (2/25)x + 35

(1/10 - 2/25) x = 35

x = 35*50

= 1750

To cross check :

8% of 1750 = 140

10% of 1750= 175

so, if he had sold for 175 instead of 140 i.e. 35 rupees more, gain will be 10%
