Solution

The correct option is B 4.29
As we know ,

$A r i t h m e t i c m e a n = E s t i m a t e d m e a n + A v e r a g e o f d e v i a t i o n s = E s t i m a t e d m e a n + \frac{Sum of deviations}{Number of Observations}$

$M e a n d e v i a t i o n = \frac{Sum of deviations}{Number of Observations}$

= $\frac{150}{35}$ = 4.29
