A) \[\frac{10}{3}\]
B) \[\frac{4}{3}\]
C) \[\frac{1}{2}\]
D) \[\frac{2}{3}\]
Correct Answer: B
Solution :
Since mean is a linear operation, after taking product with the same number and subtracting the same number, the mean becomes\[75\lambda -25\]. We thus have by the condition given in the problem\[75\lambda -25=75\Rightarrow \lambda =\frac{4}{3}\].You need to login to perform this action.
