Answer 2

The cost price of cellphone is Rs. 2500.

Given - Loss and profit

Find - Cost price

Solution - Let the CP be x.

Finding selling price in case of loss -

S.P. = (100-L)/100*CP

SP = $\frac{(100 - 10)}{100} x$

SP = $\frac{90}{100} x$

SP = 0.9x

Finding selling price in case of profit -

S.P. = (100+P)/100*CP

SP = $\frac{(100 + 10)}{100} \times x$

SP = $\frac{110}{100} \times x$

SP = 1.1x

Now, as per the question -

0.9x + 500 = 1.1x

500 = 1.1x - 0.9x

500 = 0.2x

$x = \frac{500}{0.2}$

$x = 2500$

Hence, the cost price of cell phone is Rs. 2500.
