X $ Y means X is the son of Y

X * Y means X is the wife of Y

X @ Y means X is the daughter of Y

Y % X means X is the grand daughter of Y

Which of the following shows that E and K are siblings?

Solution

✅ Correct Option: 3

In option 3: E is the son of A, A is the son of U, U is the wife of J, and K is the granddaughter of J.

So U and J are a couple with son A, and E is A's son. K, being J's granddaughter, is A's daughter. Hence E and K are siblings.

The other options are inconsistent, for example option 1 makes A both a granddaughter and a son, and option 2 makes U both a daughter and a husband.
