let age of kamal and sudhir be k and s respectively.
according to question, (k-1)/(s-1)=4/5
and (k+1)/(s+1)=5/6.
solve both equations
k=9
ad s=11
so sudhir age is 11 years.

Let the present ages of Kamal & Sudhir be x & y years respectively.
Here, x-1/y-1 = 4/5
=>5x-4y=1 ------------(i)

And,x+1/y+1 = 5/6
=>6x-5y=-1 --------------(ii)

On solving (i) & (ii),
x =9 & y = 11
The present age of Sudhir is 11 years.

RISHABH   8 years AGO

Let Kamal's and Sudhir's age 1 year ago be 4x and 5x years respectively. Then,
Kamal's age 1 year hence = (4x+1)+1 = (4x+2)years
Sudhir's age 1 year hence = (5x+1)+1 = (5x+2)years
So, 4x+2/5x+2 = 5/6
=> 24x+12 = 25x+10 => x=2
So, Sudhir's present age = 5*2+1 = 11

one year ago ages ratio is 4:5
one year hence ratio is 5:6
Since the difference between (4,5) and (5,6) is 1
and we have two years time we can take it as
2parts-->1year
then ,one year ago sudhir's age was (5*2=10)years
now the present age is 10+1=11 years

RAVAL   8 years AGO

1 year ago, kamal & sudhir's age was 4x, 5x respectively.
so, 1 year hence ratio becomes 4x+2 to 5x+2 which is equal to 5 to 6.
(4x+2/5x+2)=(5/6)
x=2
sudhir's present age= 5*2+1 = 11 years

subhashree   8 years AGO

from the ratio sudir's age 1 year ago should be multiple of 5 and one year hence should be multiple of 6.so 11 on reducing by one year becomes 10 snd adding 1 year gives 12. Thus condition is satisfied. hence option is 3.
