On selling 30 caps, a shopkeeper earns profit equal to the selling price of 3 caps. What is the profit percentage?1). 12.52). 11.113). 104). 14.28

Answer»

Let SP of 1 cap = 1

So, SP of 30 cap = 30

We KNOW that,

SP - CP = PROFIT

⇒ 30 -CP = 3

⇒ CP = 27

∴ Profit % = (SP - CP)/CP × 100 = (30 - 27)/27 × 100 = 3/27 × 100 = 11.11%
