Question

a radio was sold for rs 540 making a loss of 10%.what would be its selling price so that the profit is 10%?

Answer 1

Here your answer✍️

SP of Radio=₹540
Loss in it=10%

Let CP=₹x
A/Q
x-(x×10%)=540
x-(x×10/100)=540
x-x/10=540
10x-x/10=540. (LCM=10)
9x/10=540
x=540×10/9
x=₹600

CP=₹600
SP at Gain =10%

=600+(600×10%)
=600+(600×10/100)
=600+60
=₹660

SP should be=₹660. .To gain 10%
