Question

25. Anwar sold two washing machines at Rs. 12000 each. On one he gains 25% and on the other he loses 25%.
How much does he gain or lose in the whole transaction?

Answer 1

Answer:

For 1st machine,

x +  \frac{x}{4}  = 12000 \\  \frac{5x}{4}  = 12000 \\ x = 9600

Hence, profit on 1st machine =2400 rs.

For 2nd machine,

y -  \frac{y}{4}  = 12000 \\  \frac{3y}{4}  = 12000 \\ y = 16000

Hence loss on 2nd machine =4000 rs.

Hence total loss/profit=4000-2400

=1600 rs loss
