A mobile phone is sold for $3,120 at a loss of 4%. What will be the gain or loss percentage if it is sold for$ 3,120​

Answer»

Solution: Here, S.P. = 3,120

Loss= 4%

C.P. = 100*S.P.

100-loss%

= $100*3,120

100-4

= $100*3120

96

= $ 3,250

Now, new S.P. = $3,640

Gain = S.P. - C.P.

= $ 3,640- $ 3,250= $ 390

Hence, Gain%= Gain * 100

C.P.

= 390 * 100

3,350

= 12%

Hope it will help you.
