Sum

Raju sells a watch at a 5% profit. Had he sold it for Rs.24 more; he would have gained 11%. Find the cost price of the watch.

#### Solution

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.100/6xx24

= Rs.400
