Question

Age of Rahul is 14 years, age of arya is 10 years, age of vivek is 6 years. find the average age of them.​

Answer 1

Answer:

Given, the mean of the age of three students Vijay, Rahul and Rakhi is 15 years

So, n=3

Now, the sum of ages of the 3 students =15×3=45

Also, given ratio of their ages is 4:5:6

Sum of ratios =4+5+6=15

Hence

Vijay's age=(45/15)×4=12years

Rahul's age=(45/15)×5=15years

Rakhi's age=(45/15)×6=18years

Answer 2

Answer:

The average age of them. is 10 year.

Step-by-step explanation:

As per the data given in the question,

It is given that Age of Rahul is 14 year,

Age of Arya is 6 year,

And the age of Vivek is 6 years,

We have to find the average age of them,

Thus average is the sum of total number divided by total number,

Average age is,

$=\frac{14+10+6}{3} \\=\frac{30}{3}\\=10$

The average age of them. is 10 year.
