Question

A vendor bought 50 dozens at Rs. 10 per dozen. 2 dozen of oranges were rotten. He sold the remaining at a rate of Rs. 0.90 per orange. find his gain or loss percent

Answer 1

No of dozen of - 50
Cost of 50 dozen -50×10=500
No of rotten dozen -2
Selling price of remains dozen-0.90×12×48=518.4
Profit - 518.4-500=18.4
Gain percent - (18.4/500)100=3. 68%

Answer 2

Answer:

3.68%

Step-by-step explanation:

Given : A vendor bought 50 dozens at Rs. 10 per dozen. 2 dozen of oranges were rotten.

To Find :He sold the remaining at a rate of Rs. 0.90 per orange. find his gain or loss percent

Solution:

Cost price of 1 dozen of oranges = Rs.10

Cost price of 50 dozen of oranges = $10 \times 50$

                                                         =Rs.500

Now dozen of oranges were rotten. He sold the remaining

Remaining oranges = 50 - 2 = 48 dozens

He sold the remaining at a rate of Rs. 0.90 per orange

Selling price of 1 orange = Rs. 0.90

Selling price of 12 oranges (=1 dozen) = $0.90 \times 12=10.8$

Selling price of 48 dozen of oranges  = $48 \times 10.8=518.4$

CP = Rs.500

SP = Rs.518.4

SP>CP

So, Profit

Profit% = $\frac{SP-CP}{CP} \times 100$

Profit% = $\frac{518.4-500}{500} \times 100$

Profit% = $3.68\%$

Hence his gain percent is 3.68%
