The C.P of two watches taken together is Rs 840. If by selling one at a profit of 16% and the other at a loss of 12%, there is no gain or loss in the whole transaction then find the C.P of each watch.(PLZ answer soon exam is approaching)

Let the CP of first watch be Rs *x.*

*∴*CP of the second watch =

The first watch is sold at a profit of 16% and the second watch is sold at a loss of 12%.

∴SP of first watch

SP of second watch

According to the question, There is no gain or loss in the whole transaction.

Therefore, CP of first watch = *x* = Rs 360

CP of second watch = 840-*x = *840-360 = Rs 480
