Question

The average of the present ages of sachin and saurab is 36 year. If sachin is 8 year older than saurabh, what is the saurabh present age

Answer 1

Answer:

Step-by-step explanation:-

Let the age of Sachin be 'X'

Let the age of Saurabh be 'y'

Average age=36yrs

Sum of their ages=36×2

=72

Therefore x+y=72.......................(1)

Sachin is 8yrs older than Saurabh

Therefore, x=y+8

x-y=8.........................(2)

Now adding (1) and (2)

i.e:- x+y=72 and

x-y=8

2x=80

Therefore x=40

x+y=72

40+y=72

y=72-40

y =32

Age of Sachin=x=40years

Age of Saurabh=y=32years
