Question

a man bought 4 dozen pens at RS 7.20 a dozen .he later sold them for 65 Paisa each .find his profit %.​

Answer 1

Answer:

Profit % is 8.3%

Step-by-step explanation:

Cost of 1 dozen pens = Rs 7.20

Cost of 4 dozen pens $=4 \times 7.20 = Rs\hspace{0.1cm}28.8$

Now, Selling price of 1 pen = 65 paisa = Rs 0.65

Selling price of 4 dozen pens $= 4 \times 12 \times 0.65 = Rs\hspace{0.1cm}31.20$

Now, selling price is more than cost price.

Thus, profit is incurred

Now, Profit = Selling Price - Cost Price

Profit = Rs 31.20 - Rs 28.80

Profit = Rs 2.40

$Profit \% = (\,\frac{Profit}{CP} \times 100)\,\%\\\\ Profit\% = (\,\frac{2.40}{28.2} \times 100})\,\%\\\\Profit\% = 8.3\%$

Answer 2

Step-by-step explanation:

A man bought 4 dozen pens.

At price Rs 7.20 a dozen.

Price of 4 dozen pens=4×7.20

=28.80 rupees

Price of each pens=7.20/12

=0.60 rupees

A man sold each pen for 65 paisa

Means 0.65 rupees.

Profit on each pen=0.65-060

=0.05 rupees

Profit on 4 dozen pens=48×0.05

=2.40 rupees

Profit=percent/100 (28.80)

2.40= percent /100 (28.80)

2.40×100/28.80=percent

240/28.80=percent

percent=8.33

Profit=8.33%
