Question

Prem 150 dozen pencil at rupees 20 per dozen his overhead expenses were rupees 200 is sold them at the rate of 2.40 each what was his profit or loss percentage​

Answer 1

CP of 1 dozen=Rs.20

CP of 150 dozens=20×150

=3000/-

Overhead exp.=Rs.200

Total CP(TCP)=3000+200

=3200

SP of 1 pencil=Rs.2.40

SP of 150 dozens=2.40×12×150

=Rs.4320

Profit=SP-TCP

=4320-3200

=1120/-

Profit%=Profit/TCP×100

=1120/3200×100

=35%

Answer 2

Question:

Prem 150 dozen pencil at rupees 20 per dozen his overhead expenses were rupees 200 is sold them at the rate of 2.40 each what was his profit or loss percentage ?

Solution:

C.P. of 1 dozen pen-pencils = $₹20$

∴ C.P. of 150 dozen pen-pencils = $₹20 \times 150 = ₹3000$

Actual C.P. = $₹3000$ + overhead expenses = $₹3000 + ₹200 = ₹3200$

S.P. of 1 dozen pen-pencils = $₹2.40 \times 12 =₹28.80$

∴ S.P. of 150 dozen pen-pencils = $₹28.80 \times 150 = ₹4320$

Profit = S.P. - C.P. = $₹4300 - ₹3200 = ₹1120$

∴ Profit % $= ( \dfrac{Profit}{c.p.} \times 100)\% = ( \dfrac{1120}{3200} \times 100) = 35\%$
