SSC CGL Model Paper 19

Concept:Use the given symbol meanings to build the family tree step by step.Explanation:Given expression: $C + A \times E - F \div T \div Y - L$.$C + A$: $C$ is daughter of $A$.$A \times E$: $A$ is mother of $E$.So $A$ is mother of both $C$ and $E$.$E - F$: $E$ is brother of $F$.$F \div T$: $F$ is son of $T$.So $T$ is father of $E$ and $F$.$T \div Y$: $T$ is son of $Y$.$Y - L$: $Y$ is brother of $L$, so $Y$ is male.Thus $Y$ is father of $T$.Since $T$ is father of $C$ through mother $A$, $Y$ is $C$'s father's father.Therefore, $Y$ is the paternal grandfather of $C$.Answer:$Y$ is the paternal grandfather of $C$.
