Question

a) S.P. = 330, gain = 15%​

Answer 1

Explanation:

Let the C.P of the table be Rs. 100.

We have, Gain =10%=10% of Rs. 100=Rs. 10

∴S.P=C.P+Gain=Rs.(100+10)=Rs.110

Now, if the S.P is 110, then the C.P=Rs.100

If the S.P is Rs. 1, then the C.P =

110

100

If the S.P is Rs. 330, then the C.P =Rs.

110

100×330

=Rs.300

Hence, the C.P of the table is Rs.300.
