Question 110

‘A’ is taller than ‘B’. ‘C’ is taller than ‘D’, ‘D’ is taller than ‘E’. To determine who among them is the tallest, which of the following further information, if any, is required?

Solution

We know that: A>B, C>D, and D>E.

To know who is taller, we need a link connecting A>B to the other two conditions.

1. Even if A is taller than E and D, we don't know about its relation with C. Hence, we cannot find the tallest person.

2. Even if C is taller than B, we cannot deduce the taller person among A and C. Hence, this is an incorrect choice.

3. Even if A is taller than D, we cannot deduce the taller person among A and C. Hence, this is an incorrect choice.

4. If E is taller than A, we know that C will be the tallest. Hence, this is the correct choice.
