- We need to find how much of the 120 kg wheat was sold at a 10% gain.

- Suppose "x" kg was sold at 10% gain and "y" kg at 25% gain. Thus, x + y = 120 kg.

- The total gain was 15%. So, the equation is: (10% of x) + (25% of (120 - x)) = 15% of 120.

- Simplifying, we get 0.1x + 0.25(120 - x) = 18 (since 15% of 120 is 18).

- Solve: 0.1x + 30 - 0.25x = 18; 30 - 18 = 0.15x; 12 = 0.15x; x = 80.

- Therefore, 80 kg was sold at a 10% gain.

Correct Answer: Option: 4 - 80 kg
