Solution
The correct option is D 10
From the graph, we get the following table.
Wages (Rs.) Number of workers 800-810 3 810-820 2 820-830 1 830-840 9 840-850 5 850-860 1 860-870 3 870-880 1 880-890 1 890-900 4
The workers who earn more than 850 are n(850−860)+n(860−870)+n(870−880)+n(880−890)+n(890−900)=1+3+1+1+4=10
From the graph, we get the following table.
| Wages (Rs.) | Number of workers |
| 800-810 | 3 |
| 810-820 | 2 |
| 820-830 | 1 |
| 830-840 | 9 |
| 840-850 | 5 |
| 850-860 | 1 |
| 860-870 | 3 |
| 870-880 | 1 |
| 880-890 | 1 |
| 890-900 | 4 |
The workers who earn more than 850 are n(850−860)+n(860−870)+n(870−880)+n(880−890)+n(890−900)=1+3+1+1+4=10
