Question

on the selling of the calculater for RS 1400 a man gains 6% for how much should he sold the calculator = 15% ?

​

Answer 1

Answer:

Suppose the original price of calculator is x.

Gain percentage = 6%

Selling price = 1400

So we have the selling price of calculator as;

=>x+x×6/100 = 1400

=>x+3x/50 = 1400

=>53x/50 = 1400

=>x = 1400×50/53

=> 1320.75

So the original price of calculator = Rs.1320.75

Now, to make a profit of 15%.

Selling price =>1320.75+1320.75×15/100

=>1320.75+198.11

=> Rs.1519

Therefore,

Selling price of calculator must have Rs.1519 to make a profit of 15%
