Question

by selling two electric room heaters for Rs 3240 each,harsh makes profit of 8% on one and a loss of 10% on the other.find the total loss or gain%.

Answer 1

In the first he suffers from the loss of 3240-3000= 240

In the second he suffers from the profit of 3600- 3240= 360

profit is more than loss the he gets profit of 360 - 240= 120

$profit \: percent \: = \times \frac{profit \times 100}{cp}$
profit = 120
cp = 3600- 3000= 600


p% = 20%
