Question

3. A man purchased a cell phone for 2.000. By pay 200rs more, he replaces its body
(case). If he sells the cell phone for 2500rs, find his profit or loss per cent.​

Answer 1

Net CP = Cost of phone + Cost of repairs

= ₹2000 + ₹200 = ₹2200

SP = ₹2500

As

SP > CP

There is net gain

Gain = SP - CP = ₹2500 - ₹2200 = ₹300

Now to find Gain% simply divide the gain by CP and multiply it by 100

i. e.

$\frac{300}{2200} \times 100 = 13.63........\%$

Thus Gain% is 13.63%
