Nine individuals are sitting on the dais, from left to right, to receive an award at a local club. The awardees include at least one from each of five age groups: children, teenagers, young adults, middle-aged adults, and senior citizens. The first or the last seat is occupied by a senior citizen, who is the only individual in that age group. No two individuals from the same age group are sitting next to each other. For example, no young adult is sitting next to another young adult. There are more middle-aged adults than individuals of any other age group. There are fewer teenagers than children, young adults, or middle-aged adults. The first three individuals from the left are a young adult, a teenager, and another young adult.
In the table, select the age group of the
Fifth individual from the left and the age group of the
Seventh individual from the left. Make only two selections, one in each column.
Here start by creating the 9 spaces where the individuals will sit, now the conditions are as follows.
1. The first or the last seat is occupied by a senior citizen AND There is only 1 Senior citizen in the group.
2. No two individuals from the same age group are sitting next to each other.
3. There are more middle-aged adults than individuals of any other age group.
4. There are fewer teenagers than children, young adults, or middle-aged adults.
5. The first three individuals from the left are a young adult, a teenager, and another young adult.
The 9 spaces are
_, _, _, _, _, _, _, _, _
With conditions 1 and 5 we can see that the last position will be accuired by Senior citizen. And the 1st 3 are Young adult, Teenager and Young adult.
Young adult, Teenager, Young adult, _, _, _, _, _, Senior citizen.
Now till now,
children :
teenagers : 1
young adults : 2
middle-aged adults :
senior citizens : 1
Now with with condition 3 we can assume that middle-aged adults has to be more than 2. So will take it as 3.
children :
teenagers : 1
young adults : 2
middle-aged adults : 3
senior citizens : 1
Now with 4 we can see that teenager has be lesser than children, young adults, or middle-aged adults. Thus we can take children as 2.
children : 2
teenagers : 1
young adults : 2
middle-aged adults : 3
senior citizens : 1
The above people statisfy all the conditions and adds up to 9 people. Now coming back to the arrangement we have 5 seats and 3 middle-aged adults and 2 childrens remaining. As from rule 2, No 2 people from the same group can sit next to each other, hence thee only possible combination is.
Young adult, Teenager, Young adult, middle-aged adults,
children, middle-aged adults,
children, middle-aged adults, Senior citizen.
Thus for both the columns answer will be Children.
