Five newly born babies were weighed by the doctor. Infant A was lighter than infant B. Infant C was lighter than infant D. Infant B was lighter than infant D but heavier than infant E. which infant was the heaviest?
1. Infant - E
2. Infant - D
3. Infant - B
4. Infant - C

Answer 1

Correct Answer - Option 2 : Infant - D

According to the given information:

1) Infant A was lighter than infant B.

⇒ A < B

2) Infant C was lighter than infant D. 

⇒ C < D

3) Infant B was lighter than infant D but heavier than infant E.

⇒ E < B < D

On combining all the statements, we get:

 E < B < D; A < B; C < D

Thus, D is heavier than C and B. Also, as D is heavier than B, implies, D is heavier than both A and E.

So, infant D is the heaviest.

Hence, the correct answer is "Infant - D".
