Question

12. The C.P. of two watches taken together is Rs 840. By selling one at a profit of 16% and the other at a loss of 12%, there is no loss or gain in the whole transaction. Find the individual cost prices of the two watches.​

Answer 1

Answer:

Let cost price of one watch be Rs. x

Cost price of second watch is Rs. (840 - x)

Selling price of first watch = 116x/100

Selling price of second watch = 88(840 - x)/100

According to the question,

840 = 116x/100 + 88(840 - x)/100

Solving this we get x = Rs. 360

CP of first watch is Rs. 360 and second watch is 840 - 360 = Rs. 480
