Answer 2

SOLUTION:-

Given:

Mean of 15 numbers is 27.

Sum of these numbers= 15× 27= 405

So,

Every number is multiplied by 4.

The new sum becomes:

=) 405 × 4

=) 1620

We know that, formula;

$</strong><strong>N</strong><strong>ew \: mean = \frac{</strong><strong>N</strong><strong>ew \: sum}{</strong><strong>T</strong><strong>otal \: numbers} \\ \\ = > \frac{1620}{15} \\ \\ = > 108$

Thus,

The mean of the new number is 108.
