Question

By selling 11 oranges for a rupee, a man loses 10%. How many oranges for a rupee should he sell to gain 10%?

Options

• 9

• 10

• 8

• 5

Answer 1

9

Explanation:

SP of 11 oranges = ₹ 1

SP of 1 oranges = `1/11`

Loss = 10%

CP`=100/90xx1/11` .......`[∵"CP" = ((100)/(100-"L"%))xx"SP"]`

SP at 10% Profit`=110/100xx100/90xx1/11=1/9`

i.e. 9 oranges should be sold for a rupee to gain 10%.
