Answer 1

Answer:

Cost Price of calculator = Rs 250

Step-by-step explanation:

Rahul sold a calculator at a gain of 8%. Had he sold it for rs, 10

more, he would have gained 12%. Find the cost price of the calculator​

Let say Cost Price of calculator  = C  Rs

8 % gain = (8/100)C = 0.08C  Rs

Selling Price = C + 0.08C = 1.08C  Rs

12 % gain = (12/100)C = 0.12C  Rs

Selling Price = C + 0.12C = 1.12C  Rs

1.12C = 1.08C + 10

=> 0.04C = 10

=> C = 250

Cost Price of calculator = Rs 250
