Question

Example 1: A mobile phone is sold for * 3,120 at a loss of 4%. What will be the gain or loss per cent, if it is sold for 3,640? with all clear explanation ​

Answer 1

Answer:

Here, S.P = Rs 3120, loss % = 4 %

∴C.P.=(S.P.*100)/(100-Loss)

= Rs(100*3120)/(100-4)

= Rs(100*3120)/(96)

=Rs.3250

Now, new S.P = Rs 3,640

∴ Gain = S.P - C.P = Rs 3,640 - Rs 3,250 = Rs 390

Hence, gain
