Answer:
A. Zero
Read Explanation:
No one is elder than E (the answer is 0). E is the oldest person in the group.
Let's order the 5 people by age from oldest (1st) to youngest (5th):1st (Oldest) > 2nd > 3rd > 4th > 5th (Youngest)
Step 1: Place R
"Only four people are younger than R."
Since there are 5 people in total, if 4 are younger than R, R must be the oldest.
Position:
R > ___ > ___ > ___ > ___
Step 2: Place T and A
"There are only two people who are aged between T and A."
This means there must be exactly two spaces between them (e.g., positions 2 and 5, or positions 1 and 4). Since position 1 is already taken by R, T and A must occupy positions 2 and 5.
Therefore, the positions look like this:
R > (T/A) > ___ > ___ > (A/T)
Step 3: Analyze the relationship between H, E, and A
"H is younger than E but elder than A."
This means the relative order must be:
E > H > A.Since A must have two people (E and H) older than him/her within this sub-group, A cannot be in position 2. A must be at the very bottom in position 5.
Consequently, T must be in position 2.
Updated positions:
R > T > ___ > ___ > A
Step 4: Fill in the remaining slots for E and H
We have positions 3 and 4 left open, and we know
E > H.So, E goes into position 3, and H goes into position 4.
Final Age Order
\text{R (Oldest)} > \text{T} > \text{E} > \text{H} > \text{A (Youngest)}
Looking at our final order, the people elder than E are R and T.
