1. 

Which of the following shows that A is the aunt of E?

A. A - B + C ÷ D x E
B. A x B ÷ C x D - E
C. A ÷ B x C + D - E
D. A + B - C x D ÷ E
E. None of these

Answer: Option B

Explanation:

In choice (A), generation gap is : 0 + 1 + (+1) + 0 = 2. So, A is E's grandma's generation.
In choice (B), gap is : 0 + 1 + 0 + 0 = 1.

In choice (C), gap is: 1 + 0 + 1 + 0 = 2. So, A is E's grandma's generation. So, Choices (A), (C) and (D) are eliminated.

Correct choice: (B).
