Question 63

Average of 12 numbersis 48. If each numberis increased by 11, then what will be the new average?

Solution

average =$$\frac{ sum of no.}{total no.}$$

48 = $$\frac{ sum of no.}{12}$$

Sum of no.= 576

If each no. Is increased by 11

So, $$11\times12$$= 132

New avg = $$\frac{ sum of no.}{total no.}$$

New avg = $$\frac{ 576+132}{12}$$

= 59
