Explanation:
- Step 1: Determine Sue's cost price.
- Rima buys the watch for Rs 2,178 at a 10% profit for Sue.
- Let Sue’s cost price be x.
- x * 1.10 = 2,178, hence x = 2,178 / 1.10 = 1,980.
- Step 2: Determine John’s cost price.
- John sold to Sue at a 20% profit, so let John’s cost price be y.
- y * 1.20 = 1,980, hence y = 1,980 / 1.20 = Rs1,650.
- Correct Answer: Option 1 – 1,650.
