The final loss percent is 0.25%.
What is the final loss percent?
The gap between the cost price and the selling price is what is referred to as a loss. And the loss percent is the loss as a percentage of the actual cost.
Total CP=Rs. 400
Let the CP of the first watch be Rs. x
So, CP of the second watch=Rs.(400-x)
For the first watch,
Gain Percent=5%
SP = [tex](1+\frac{5}{100})*x[/tex]
SP=105x/100
For the second watch,
Loss Percent=5%
SP=[tex](1-\frac{5}{100})(400-x)[/tex]
SP=95(400-x)/100
As the SP of both the watches is the same.
[tex]\frac{105}{100}x=\frac{95}{100}(400-x)[/tex]
105x=38000-95x
105x+95x=38000
200x=38000
x=38000/200
x=190
CP of the first watch=Rs. 190
CP of the second watch=Rs. (400-190)=Rs. 210
SP of first watch=[tex]\frac{105}{100}*190[/tex] =Rs. 199.50
SP of second watch=[tex]\frac{95}{100}*210[/tex]=Rs. 199.50
Total SP=Rs. 399
Final Loss=Total CP-Total SP
=Rs.(400-399)
=Rs. 1
Final Loss Percent=100/400
=0.25%
