Question

Mohit is 6 years older than sourav after 5 years mohit will be twice the age of sourav then find their present age

Answer 1

Let Sourav age be X years

then Mohit age x-6 years
By a\q
After 5 years Sourav age will be X+5 years
And Mohit age will be X-6+5 years
so Mohit age x-1 years
But
2(X+5) = x-1
2x+10= x-1
X= 11 years

Answer 2

suppose age of mohit=x
age of sourav=y
Acc.to question
x=y+6
x-y=6.......1

after 5 years age of mohit=x+5
after 5 years age of sourav =y+5
so Acc.to question x+5=2(y+5)
x+5=2y+10
x-2y=10-5
x-2y =5......2
by elimination method
x-y=6
x-2y=5
substract equation 2 from 1
so x-y=6
x-2y=5
- + -
signs changes due to subtraction
0+y=1
y=1..
put value of y in equation 1 or 2 to get value of x
x-y=6
x-1=6
x=6+1
x=7
so age of mohit=7
and age of sourav=1
