Question

2) If apples are bought at 11 for RS 10 & sold at 10 for RS 11, how much will be the gain %? a) 5% b) 4% c) 3% d) 2%

Answer 1

Thanks for the question!!!


Cost of 11 apples = Rs.10/-

Selling Price of 11 apples
=11/10*11
=121/10

Therefore, Profit = 121/10 - 10
                           = 21/10 gain %
                           = 21/10 / 10 * 100
                           = 21/100 × 100
                           = 21 % Profit

Answer 2

Answer:

The gain percentage is 21%.

Step-by-step explanation:

Given : If apples are bought at 11 for RS 10 & sold at 10 for RS 11.

To find : How much will be the gain %?

Solution :

The cost price of 11 apples = Rs.10

The cost price of 1 apple = $\frac{10}{11}$

The selling price of 10 apples = Rs.11

The selling price of 1 apple = $\frac{11}{10}$

The gain is Gain=SP-CP

$G=\frac{11}{10}-\frac{10}{11}$

$G=\frac{121-100}{110}$

$G=\frac{21}{110}$

Gain percent formula is given by,

$G\%=\frac{G}{CP}\times 100$

$G\%=\frac{\frac{21}{110}}{\frac{10}{11}}\times 100$

$G\%=\frac{21\times 11\times 100}{110\times 10}$

$G\%=21\%$

Therefore, The gain percentage is 21%.
