Answer 1

after 5year
=14year+5year

Answer 2

Answer:

The average age of 5 students after 5 years  = 19

Step-by-step explanation:

Given,

The average age of 5 students today  = 14years

To find,

The average of the students after 5 years

Recall the concepts

Average = $\frac{Sum \ of \ observations}{Total \ no\ of \ observations}$

Solution

Since The average age of 5 students today  is 14 years

Then we have

14 = $\frac{Sum \ ages \ of \ 5 students}{5}$

Sum of ages of 5 students  = 14×5 = 70

After five years,

The sum of ages of 5 students after 5years = 70 + 5×5

= 70 + 25

= 95

The sum of ages of 5 students after 5years = 95

The average age of 5 students after 5 years

= $\frac{Sum \ ages \ of \ 5 students \ after \ 5\ years}{5}$

=  $\frac{95}{5}$  

= 19

∴ The average age of 5 students after 5 years  = 19
