By selling a watch on 400 and 460’. Loss and profit happened respectively. if the loss and profit are equal, find cp.

430

Step-by-step explanation:

Given :-

And we need to find out the CP .So ,

Let :-

According to the Question :-

460 = x + y ( Profit)

400 = x - y ( Loss)

Adding both :-

460 + 400 = x + y + x - y

860 = 2x

x = 860/2

x = 430

Hence the Cost price of the watch is 430 .
