As it is ratio of 4:7
So we can keep a variable
Krishna = 4x
Abdul= 7x
Age before 5 years
Krishna= 4x-5=11
Abdul= 7x-5
4x-5=11
4x=16
X=4
There age after 6 years
Krishna = 4x +6
Abdul= 7x +6
So there age after 6 years is
Krishna is 22 yrs old
Abdul is 34 yrs
So we can keep a variable
Krishna = 4x
Abdul= 7x
Age before 5 years
Krishna= 4x-5=11
Abdul= 7x-5
4x-5=11
4x=16
X=4
There age after 6 years
Krishna = 4x +6
Abdul= 7x +6
So there age after 6 years is
Krishna is 22 yrs old
Abdul is 34 yrs

Step-by-step explanation:
given that the ratio is 4:7
let their present ages be 4x and 7x respectively
now,
given that 5 years ago krishna was of 11 yrs old
so (present age -5 years )=11
> 4x-5=11
> 4x=11+5
> 4x=16
> x=4
so present age of krishna is 4*4 =16 yrs
and abdul age is 7*4= 28 yrs
now the age after 6 years will be
krishna=16+6=22
abdul=28+6=34
now the ratio after 6 yrs would be
22:34
=11:17
