Read the information given below and answer the questions that follow:
i. A * B means -> A and B are of the same age
ii. A - B means -> is younger than A
iii. A + B means -> A is younger than B
X + Y + Z is same as _____?
Explanation
i. A * B means -> A and B are of the same age
ii. A - B means -> B is younger than A → A is older than B
iii. A + B means -> A is younger than B
X + Y + Z → X < Y < Z
1)Y - X – Z → Y > X > Z → Z < X < Y
2)Z - Y – X → Z > Y > X → X < Y < Z
3)Z - X – Y → Z > X > Y →Y < X < Z
4)X - Y – Z → X > Y > Z → X > Y > Z
So, X + Y + Z is same as Z - Y – X.
Hence, ‘Z - Y – X’ is the correct answer.
