Question

A dining table is sold at 1230 incurring a loss of 18% what would be the gain or loss per cent if it was sold for 1600?

Answer 1

Given
Sp=1230
Loss%=18%

Then
Cp=spx100/(100-loss%)

Cp=1230x100/82

Cp=1500

Now if he sells it for 1600

Cp=1500
Sp=1600
Sp>cp =profit

Profit =sp-cp

=1600-1500=100

Profit %= profit / cp x 100

Profit %=100/ 1500 x100

=10000/1500 =100/15=20/3=6 2/3 %

Profit =6 2/3% or 6.667%
