A man sells two articles at the same price, one at a gain of 20% and the other at a loss of 20%. What is the net result?

A. No loss, no gain
B. 4% gain
C. 4% loss
D. 5% loss

Solution:
Let SP = 100 each.
For 20% gain → CP = 100/1.2 = 83.33.
For 20% loss → CP = 100/0.8 = 125.
Total CP = 208.33, Total SP = 200 → Loss ≈ 8.33.
% Loss = (8.33/208.33)×100 ≈ 4% loss.
Answer: C.
