- #9Raju sells a watch at 5% profit. Had he sold it for Rs.24 more; he would have gained 11%. Find the cost price of the watch.Ans : Let C.P. of the watch = Rs.100
When profit = 5%;
S.P. = Rs.(100 + 5) = Rs.105
When profit = 11%;
S.P. = Rs.(100 + 11) = Rs .111
Difference of two selling prices = Rs. 111 - Rs. 105 = Rs.6
When watch sold for Rs.6 more; then C.P. of the watch = Rs.100
When watch sold for Re. 1 more; then C.P. of the watch = Rs. 100/6
When watch sold for Rs.24 more; then C.P. of the watch = Rs. 100/6 × 24 = Rs.400
