Question

by selling a vcd player for rs.1950 i got a profit of 30% .at what price should i sale it in order to get s profit of 40% ?

Answer 1

Selling price of the VCD player = Rs. 1950
Profit = 30%
:.Cost price = 100/(100+Profit%)×SP
= Rs. 100/130×1950
= Rs. 1500
Now,
CP = Rs. 1500
Required profit = 40%
:. SP = (100+Profit%)/100×CP
= Rs. 140/100×1500
= Rs. 2100
Hence the VCD player must be sold for Rs. 2100.
