Practice and master this topic with our carefully crafted questions.
Directions (Q. Nos. 1-4) Read the following information carefully and answer the questions given below it:
P ÷ Q means P is the father of Q
P + Q means P is the mother of Q
P - Q means P is the brother of Q
P x Q means P is the sister of Q
If A + B ÷ C - D, then A is D's
Choice (B) and (D) are wrong as A + B means A is a mother, hence a female. Generation gap between A and D is (+1) + (+1) + (0) = 2. So, A must be a grandmother.
If A x B ÷ C - D + E, then A is E's
A x B so A is a sister, hence a female. Generation gap : (0) + (+1) + (0) + (+1) = +2.
So, A is E's grandmother's generation.
Correct choice
Which of the following shows that A is the aunt of E?
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).
P - Q means Q is son of P and P x Q means P is brother of Q, P ÷ Q means Q is sister of P, and P + Q means P is mother of Q. Which of the following is definitely TRUE about N x K - M ÷ L?
So, choice (B) is correct. Note that sex of K is not known.
