Answer 1

Question ⤵️

By selling oranges at the rate of rupees 72 per dozen women losses 10% of their investment what would be the percentage of her gain or loss if she is sold at rupees 600 per hundred

Answer ⤵️

Let the cost of 1 dozen oranges be x.

By selling oranges at the rate of 72 rs per dozen a woman loses 10% of her investment

x-\frac{10}{100}x=72

0.9x=72

x=80

1 dozen = 12 oranges

The cost of 12 oranges is Rs. 80.

The selling price of 100 oranges is 600. The selling price of 12 orange is

SP=\frac{600}{100}\times 12=72

The selling price of 12 oranges is 72.

The formula for profit percentage is

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

\%=\frac{72-80}{80}\times 100=-10

Negative sign represent the loss.

Therefore the loss percentage is 10%.
