Q.801 Medium HCF and LCM

A man sells two articles. One at 20% profit and another at 20% loss. If both have the same cost price of ₹1000, what is the overall profit or loss?

A No profit, no loss

B 4% profit

C 4% loss

D 5% profit

Correct Answer: C. 4% loss

Explanation:

SP1 = 1000 × 1.2 = ₹1200. SP2 = 1000 × 0.8 = ₹800. Total SP = 2000. Total CP = 2000. Loss = 2000 - 1600 = ₹400. Wait, recalculating: Total SP = 2000, Total CP = 2000. No net = 0. Actually: When profit% = loss%, overall is always loss = (r/100)^2 × 100 = (20/100)^2 × 100 = 4% loss
