C Correct answer
Explanation

In the whole transaction, there is neither gain nor loss. Therefore, Amount of gain in one watch=Amount of loss in other watch. 0.20* CP1=0.15*CP2 CP1/CP2=0.15/0.20=3/4 Also CP1+CP2=560 Hence, CP1=3/(3+4) * 630
CP1=270 And CP2=630-270=360 Therefore, cost is Rs. 270 and Rs. 360 It is the correct answer.
