Following question is based on the information given below:
(i) 'R×S' means 'R is father of S'
(ii) 'R-S' means 'R is sister of S'
(iii) 'R+S' means 'R is mother of S'
(iv) 'R÷S' means 'R is brother of S'
In the expression A+B×C÷D how is C related to A?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Grandson
Each symbol stands for one relation; read every pair as “the left letter is the … of the right letter”. The codes are:
R × S: R is the father of S
R − S: R is the sister of S
R + S: R is the mother of S
R ÷ S: R is the brother of S
Breaking A + B × C ÷ D into pairs:
A + B: “+” means mother, so A is the mother of B.
B × C: “×” means father, so B is the father of C.
C ÷ D: “÷” means brother, so C is the brother of D; this pair shows that C is male.
A is the mother of C’s father, so A is C’s grandmother, and C, being male, is A’s grandson.
