A shopkeeper buys 1 dozen of pen at Rs. 144, and sells them at Rs. 15 each. Which of the following is the profit amount

Answer 1

TO FIND:-

profit amount = $180-144$ ⇒ ₹$36$

GIVEN:-

A shopkeeper buys 1 dozen (1 dozen=12) of pen at Rs. 144 ← (C.P.)

He sells them at Rs. 15 each ← (S.P.)

TO FIND:-

the profit amount

SOLUTION:-

cost of 12 (1 dozen) of pen (C.P.) = ₹ 144

∴ cost of 1 pen = $\frac{144}{12}$ ⇒ ₹$12$

∴ cost of 12 pens that he sold (S.P.) = $12$×$15$ ⇒ ₹$180$

hence

$S.P.>C.P.$ means profit

profit amount = $180-144$ ⇒ ₹$36$
