Preeti bought 45 dozen oranges at Rs. 60 per
dozen. Ten percent of oranges were rotten and
could not be sold. At what rate should she sell
the remaining oranges, so as to earn a profit of
10%?​

Answer 1

Step-by-step explanation:

1 dozen =12 oranges

45 dozen =45*12= 540

540/100*10 = 54

54*5 =270

Answer 2

The remaining oranges should be sold at the rate of Rs. 73.33 per dozen.

Step-by-step explanation:

Given:

• 45 dozen oranges bought at the rate of Rs. 60
• 10% of oranges are found to be rotten

To find: The rate at which a profit of 10% can be earned

Solution:

• Cost Price of 45 dozen oranges $= 45\times 60 = 2700$ Rs

• Expected Profit $= 10\% of CP = \frac{10}{100}\times 2700 = 270$

• So, Selling Price, SP = CP + Profit $= 2700 + 270 = 2970$ Rs

• Total number of oranges bought $= 45 \times 12 = 540$

Number of rotten oranges $= 10\% = \frac{10}{100} \times 540 = 54$

Number of oranges left to be sold $= 540 - 54 = 486$

Dozen of oranges to be sold $= \frac{486}{12} = 40.5$

• Thus, 40.5 dozens of oranges need to be sold for 2970 Rs

So, one dozen can be sold at the rate $= \frac{2970}{40.5} = Rs 73.33$

The remaining oranges should be sold at the rate of Rs. 73.33 per dozen.
