The mean of terms is . If the first term is increased by , second by and so on, then the new mean is
Explanation for the correct option.
Find the new mean.
It is given that, the mean of terms is .
Assume that, the terms are .
Therefore, .
Since, it is given that the first term is increased by , second by and so on.
That means, the terms become .
So, the new mean is as follows:
From equation .
Therefore, the new mean is .
Hence, option is the correct option.
