Question

micheka bought pens at rs 120 a dozen.he sold it for rs 15 each. what is his profit per cent?

Answer 1

cost of 12 pens(a dozen) = 120

selling price of 1 pen = 15

selling price of 12 pens = 12*15 = 180

profit = sp - cp = 180 - 120 = 60

profit % = profit / cp * 100

= 60/120*100

= 50%

Answer 2

Solutions :-



[ 1 Dozen = 12 Units ]

Given :-

Micheka bought pens at rs 120 a dozen.

Cost price (C.P) of 1 pen = Rs 120/12 = Rs 10


Selling price (S.P) of pen = Rs 15



Selling price is greater than the cost price.

Therefore, Profit

Profit = S.P - C.P
= Rs ( 15 - 10)
= Rs 5


Profit % = (profit × 100)/C.P %
= (5 × 100)/10 %
= 500/10 % = 50%


Hence,
Profit percent is 50%
