Question

A shopkeeper buys pencil at the rate of 10 pencils for rupees 25 and sells them at 12 pencil for 37 find his gain or loss percent

Answer 1

Cost of 10 pencils = Rs.25

Cost price of each pencil = Rs.25/10=Rs.2.5

Selling price of 12 pencils =Rs.37

Selling price of each pencil = 37/12 =Rs. 3.08

Gain = 3.08-2.5=Rs.0.58

Gain percent= Gain/Cost price *100= 0.58/1 *100=58%

Answer 2

buy the 10 pencil at the rate of 25
than rate of one pencil is 2.5
now he sell 12 pencil at the rate of 37
rate per pencil of sell 3.08
terefore profit per pencil is 0.58
now profit on 10 pencil is 5.8 rupees
now profite % is 5.8 ×100/25 =23.2%
