Answer 2

Answer:

1400₹

Step-by-step explanation:

Let cost price of the watch for Gopi = CP

Now Gopi sold it to Ibahim at 12% gain

Then,

Cost price for Ibrahim will be = CP + 12% of CP

= CP + 0.12CP= 1.12 CP

Now Ibrahim sold it to John at 5% loss and John paid 1330₹

Then,

Cost price for John = 1.12CP - 5% of 1.12CP

1330₹ = 1.12CP - 0.056 CP

CP = 1250₹

Gopi had bought the watch for 1250₹

So Gopi sold it in = 1.12 × 1250₹ = 1400₹
