Question

by selling a stool for rupees 67.50 a carpenter losses 10% how much percent would he gain or loss by selling it for rupees 82.50

Answer 1

Here sp = 67.50, Loss = 10 %. first calculate cp. In this type of questions where sp and profit/loss % is given, use the below formula to calculate cp. Cp= sp*100/(100 + profit % /loss %).

Cp = 67.5*100/(100-10) = 6750/90 = rs 75

Let us find his gain or loss if he sells it for rs 82.5. Here his sp is 82.5 and the cp is 75. So his gain = 82.5-75 = rs 7.5.

Gain % = 7.5*100/75 = 10 %.

Happy now.
