Question

The average age of mukesh, ramesh, and suresh 3 years ago was 27 years and that of ramesh and suresh 5 years ago was 20 years. The present age of mukesh is:

Answer 1

present total ages of mukesh, ramesh, and suresh = 3*27+3 =90

present total ages of  ramesh and suresh = 2*20+5 = 50

so from the above we can get mukesh age = 90-50= 40

Answer 2

Answer:

The present age of Mukesh is 40 years old.

Step-by-step explanation:

Let, the present age of Mukesh = x

      the present age of Ramesh = y

      the present age of Suresh = z

Now,

three years ago

Mukesh's age was (x-3)

Ramesh's age was (y-3)

Suresh's age was (z-3)

according to question  : $\frac{(x-3)+(y-3)+(z-3)}{3}$=$27$

⇒$(x-3)+(y-3)+(z-3)=81$

⇒$x+y+z= 90$     eq.................1.

And,

five years ago

Ramesh's age was (y-5)

Suresh's age was (z-5)

∴ $\frac{(y-5)+(z-5)}{2} =20$

⇒$y+z= 50$     eq.........................2

Now, putting eq........2 in eq.......1

we get,

$x+50= 90\\x=40$

It was assumed that the present age of Mukesh is 'x' so now getting the value of 'x' as 40. Therefore the present age of Mukesh is 40 years old.
