Question

Gopi sold a watch to Ibrahim at 12% gain and Abraham sold it to John at a loss of 5% If John paid 1331 find how much did Gopi sold it

Answer 1

John paid for the watch = Rs.1330 i.e. this cost price of watch for john is also selling price of the watch for Ibrahim.

cost price of the watch for Ibrahim will be :-

cost price = (100 × selling price) ÷ 100 - loss %

cost price = (100 × 1330) ÷ 100 - 5

= 133000 ÷ 95

cost price for Ibrahim = Rs. 1400

Hence cost price of watch for Ibrahim = selling price of watch for Gopi.

So Gopi sold it to Ibrahim for Rs. 1400.
