Solution:

Let the cost price be Rs. 100
Now, the selling price

=

Rs. 115
New CP. = Rs. 90
New S.P.

=\;{90 × 125}/{100}=R s .112 .5

The Difference in S.P.

=R s .(115-112.5)

=Rs.2.5

If the difference is Rs.

2.5,

the

C P

=R s, 100

Therefore, if the difference is Rs.

200,

the C.P.

=\;{100 × 200}/{2.5}=R s .8000
