Question

On selling 30 caps, a shopkeeper eams
profit equal to the selling price of 3 caps. What is
the profit percentage?​

Answer 1

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%
