Question

By selling a stool for Rs.67.50,a carpenter loses 10%.how much per cent would he gain or lose by selling it for Rs.82.50?

Answer 1

a stool Rs = 67.50
10 % loss = 67.50 10%
67.50 1% = 67.50/100 = 0.6750
67.50 10% =0.6750 × 10 = 6.750
= 67.50 + 6.750 = 74.25 = real price
82.50 gain or lost = gain
82.50 -74.25 = 8.25
gain Rs = 8.25
$\frac{8.25}{82.5} \times \frac{x}{100} = 10$
is have gain 10 %
