Raju 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. |

Answer» 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) x 24 = Rs.400 |
