Question

Read the information given carefully and answer the question
$x+y$ means $x$ is the sister of $y$
$x-y$ means $x$ is the son of $y$
$x\times y$ means $x$ is the mother of $y$.
$x\ne y$ means $x$ is the father of $y$.
$x÷y$ means $x$ is brother of $y$
$x=y$ means $x$ is daughter of $y$

Which of the following alternative means '$F$' is father of $J$?

• A. $F÷G\ne H\times I-J$
• B. $J=I\times +H\ne G÷F$
• C. $F+G-H\times I-J$
• D. $J+I-H\times G-F$

Answer 1

Answer: (D)

$J+I-H\times G-F$

Looking at each option one by one

Option A: From the information given it follows that J is the father of I and F is the brother of father of H. No direct relation between J and F can be inferred. Omit this option

Option B: I and H are brothers and sister. I is the mother of J while H is the father of G and F. No direct relation between J and F can be inferred. Omit this option

Option C: F is a female. But we want a relationship where F is father (male). Omit this choice

Option D: This the remaining and correct choice. From the statement it follows that F and H are father and mother respectively of J, I and G.

Option D is correct
