A man sod his watch at a loss of 5% . Had he sold it for TK. 56.25 more he woud hae gained of 10% . The cost price of the watch is - Correct Answer TK. 375
Selling price at 5% loss = 100 - 5 = 95 TK. Selling price at 10% gain = 100 + 10 = 110 TK Difference in selling price = 110 - 95 = 15 TK. For the selling price being 15 TK more than initial, the actual cost price = 100 TK. For the selling price being 56.25 TK more than initial, the actual cost price = 100 x 56.25 / 15 = 375 TK
