उत्तर
Classes: 2.1 - 4.0, 4.1 - 6.0 and 6.1 - 8.0
Since classes are inclusive, we have
Adjustment factor
= `(4.1 - 4.0)/(2)`
= `(0.1)/(2)`
= 0.05
| True Lower Limit | True Upper Limit | Class - Mark |
| 2.1 - 0.05 = 2.05 | 4.0 + 0.05 = 4.05 | 3.05 |
| 4.1 - 0.05 = 4.05 | 6.0 + 0.05 = 6.05 | 5.05 |
| 6.1 - 0.05 = 6.05 | 8.0 + 0.05 = 8.05 | 7.05 |
