Marks: +1, -0

A shopkeeper sold two items. The selling price of the first item equals the cost price of the second item.
He sold the first item at a profit of

20 \%

and the second item at a loss of

10 \%

. What is his overall profit\/loss per cent?

Solution:

Let CP of first item

=₹ 100

Then,

{SP}=( {CP} × \;{100+P \%}/{100})

=100 × \;{120}/{100}=₹ 120

According to the question,
SP of first item

=

CP of second item
Now,

\;\text " SP of second item "\; \;\; = {CP} ×(\;{100-L \%}/{100})

\;\; =120 × \;{90}/{100}

\;\; =₹ 108
