A shopkeeper sells two articles for ₹1000 each, gaining 20% on one and losing 20% on the other. Overall he incurs a loss of what percent?

Question

Accepted Answer

4. Equal selling prices with equal ±x% → loss % = x²/100 = 400/100 = 4%. (Check: CPs are 1000/1.2 = 833.33 and 1000/0.8 = 1250, total 2083.33 against SP 2000 — a loss of 83.33, i.e. 4%.)
