- 201.50
- 143.50
Correct Option: D
Using Rule 25,
Skilled : half skilled : unskilled
| = | : | : | ||||
| 3 | 4 | 6 |
| = |  | × 12 |  | : | | × 12 | | : | | × 12 | | = 4 : 3 : 2 | 3 | 4 | 6 |
Share of the trained labourer
| = | × 369 | (7 × 4 + 8 × 3 + 2 × 10) |
| = | × 369 | (28 + 24 + 20) |
| = | × 369 = ₹ 143.50 | 72 |
