Answer 2

The profit percentage is 35%.

Step-by-step explanation:

Given : The MP of a camera is 3/2 of the CP and SP is 9/10 of  MP.

To find : The percentage profit or loss. ?

Solution :

Let the cost price be 'x'.

The MP of a camera is 3/2 of the CP.

i.e. market price is  $\frac{3}{2}x$

The SP is 9/10 of  MP

i.e. selling price is $\frac{9}{10}\times \frac{3}{2}x=\frac{27}{20}x$

Profit = Selling price - Cost price

$P=\frac{27}{20}x-x$

$P=\frac{27x-20x}{20}$

$P=\frac{7x}{20}$

The profit percentage is

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

$P\%=\frac{\frac{7x}{20}}{x}\times 100$

$P\%=\frac{7}{20}\times 100$

$P\%=35\%$

Therefore, the profit percentage is 35%.
