Question

Gopi sold a watch to ibrahim at 12% gain and ibrahim sold it to john at a loss of 5%.if john paid 1330 then 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.
