From the question , we know there are atleast one from each of the 5 groups
1. Senior citizen is only 1 . Since postion 1 , 2 & 3 is occupied by YA , T & YD and as per the ques , the SC can only be placed at 1st or 9th position so 9th pos- SC ; 1- YA, 2- T , 3-YA
2. No of T is less than C, YD , & MAA and a T occupies 2 nd position so T is out
3. MAA is the greatest among all and YA is already 2 so MAA has to be 3
It is only possible if 5th and 7th are C and rest of the positions are occupied by MAA
Ans : AA

The only possible combination of number of individuals is:
C = 2
T = 1
Y = 2
M = 3
S = 1
From the text we get this order:
YTY_____S
and because no two individuals from the same age group are sitting next to each other, the only possible order is:
YTYMCMCMS
So in 5th and 7th positions are the two children.
C = 2
T = 1
Y = 2
M = 3
S = 1

As per the constraints, following would be the initial setting:-
Let children = c, teenagers = t, young adults = ya, middle-aged adults = ma, and senior citizens = sc
Left to Right:-
ya, t, ya, _, _, _, _, _, sc
We put sc in last since they can only occupy first or last place, and are the only one.
Now, ma have to be the most in number, which means they have to be atleast 3 as per the current arrangement, since ya is 2. Updated arrangement:-
ya, t, ya, m, _, m, _, m, sc
Notice there isn't any other way to insert m, since we can't have two m's side by side.
It is given that there are fewer t than c, ya, or ma, which means c has to be atleast 2. Updated arrangement:-
ya, t, ya, m, c, m, c, m, sc
Hence, the fifth and seventh from left are both from the children age group.
