Q:

By selling an article at Rs.800, a shopkeeper makes a profit of 25%.At what price should he sell the article so as to make a loss of 25%?

A) Rs.720	B) Rs.640
C) Rs.540	D) Rs.480

SP = Rs.800 ; Profit = 25%

$C P = S P x \frac{100}{100 + P %} = 800 x \frac{100}{100 + 25} = 640$

Now, CP = Rs.640

Loss = 25% = 25% of Rs.640 = Rs.160

Thus, SP = CP - Loss = Rs.640 - Rs.160 = Rs.480
