Answer 2

Answer:

The approximate profit percentage is $\frac{150}{11}$%

Step-by-step explanation:

Let the selling price of the camera be Rs. x.

Then the cost price of the camera, according to the problem, is Rs. ($\frac{88}{100} x$)

Now, the profit is Selling price minus cost price.

Therefore, Profit = $x-\frac{88}{100} x \\= \frac{100x-88x}{100}\\ =\frac{12x}{100}$

Now, if cost price is $\frac{88x}{100}$ then profit is $\frac{12x}{100}$,

If cost price is 1 then profit is $\frac{\frac{12x}{100} }{\frac{88x}{100} }$ or $\frac{12}{88}$

Therefore, if cost price is 100 then profit is $\frac{12 * 100}{88}$ = $\frac{150}{11}$ %

Hence, profit is $\frac{150}{11}$%
