Answer

By formula,

Adjustment factor = $\dfrac{\text{Lower limit of one class - Upper limit of previous class}}{2}$

The given classes (30-34, 34-38, 38-42) are already in continuous (exclusive) form, as the upper limit of each class is equal to the lower limit of the next class.

⇒ Adjustment factor = $\dfrac{34 - 34}{2} = \dfrac{0}{2} = 0$ .

Hence, Option 3 is the correct option.
