Question

by selling of tool for rupees 144 a carpenter loses 10% how much percent would he gain or loss by selling it for Rs 180​

Answer 1

Given SP = 144 and Loss = 10%.

Loss=10%;

From the question selling price and loss is given, with these price we need to find the cost price.

CP=(SP×100)/Loss;

CP = 144 x 100/(100 - 10)

CP = 160

Given, SP =180 and cost price = 160

Gain = SP-CP

Gain=180-160

Gain= 20

Gain % = Gain x 100/CP

Gain % =20x 100/160

Gain= 12.5%
