Question

The average age of my family of 05 members is 40 years.Excluding me the average age is 35 year. Find my age?

Answer 1

Answer:

Step-by-step explanation:

Let the ages of all family members be a,b,c,d,e.

Where your age is 'a'.

So, according to the question,

(a+b+c+d+e)÷5 =40

Or, a+b+c+d+e= 200_____(1)

And,

(e+b+c+d)÷4 =35

Or,b+c+d+e=35×4=140______(2)

Substituting (2) in (1),

140+a=200

So,a=60

Hence, your age is 60 years.
