Question

The cost price of 12 pencils is equal to the selling price of 10 pencils. Find the profit per cent​

Answer 1

Answer:

20%

Step-by-step explanation:

LET THE COST PRICE OF 1 PENCIL BE RS. 100.

COST PRICE OF 12 PENCILS= 12×100=1200

SELLING PRICE OF 10 PENCILS = 1200

SELLING PRICE OF 1 PENCIL = 1200/10 =120 RS.

GAIN = 120-100= RS. 20.

GAIN PERCENT = 20×100/120 = 20%
