Profit 50%

Answer 2

Answer: Profit 50%

Step-by-step explanation:  

1 dozen = 20 rupees

therefore, 150 dozen = 20 x 150

                                   = 3000 rupees is cost price

Therefore, Karim bought 150 dozens of pencil for rupees 3000.

1 dozen = 12 pencils

therefore, 150 dozen = 12 x 150

                                   = 1800 pencils were bought

1 pencil = 2.5 rupees

1800 pencils = 2.5 x 1800

                     = 4500 rupees is selling price

s.p is more than c.p, therefore it is a profit.

Profit = s.p - c.p

= 4500 - 3000

= rupees 1500

Profit percent = profit / c.p x 100

=  1500 / 3000 x 100

= 150 / 3

= 50 %
