Step 1: Understanding the problem.
Gopi sold the watch to Ibrahim at a 12% gain. Ibrahim then sold it to John at a 5% loss. We are given that John paid ₹ 1,330. We need to determine the price at which Gopi sold the watch to Ibrahim.
Step 2: Let the price at which Gopi sold the watch be x.}
Gopi's selling price to Ibrahim = \( x \). Ibrahim's selling price to John = \( 0.95x \), since he sold it at a 5% loss.
Step 3: Relating the final price.
We know that John paid ₹ 1,330 for the watch, so:
\[
0.95x = 1330
\]
Solving for \( x \), we get:
\[
x = \frac{1330}{0.95} = 1400
\]
Step 4: Conclusion.
Therefore, Gopi sold the watch to Ibrahim for ₹ 1400.
Final Answer: ₹ 1400.
