Answer 1

Given info : Jainy Electronics sold a calculator at a prifit of 5 % instead a loss of 5 % loss and got Rs. 11 more.

To find : The cost price of the calculator is ..

solution : case 1 : let the cost price of calculator is 100 Rs.

profit = 5 % of CP = 5/100 × 100 = 5 Rs.

so SP = Profit + CP = 5 + 100 = 105 Rs.

case 2 : loss = 5 % of CP = 5 % of 100

= 5/100 × 100 = 5 Rs.

SP = CP - loss = 100 - 5 = 95 Rs.

The difference in sold price, SP = 105 - 95 = 10 Rs.

if the difference of sold price is 10 Rs then cost price is 100 Rs.

if the difference of solid price is 11 Rs then cost price = 100/10 × 11 = 110 Rs.

Therefore the cost price of calculator is 110 Rs.
