Which number will replace the question mark in the number bond below?

A)  34                               

B)  30                               

C)  33                               

D)  35

Correct Answer: A

Solution :

: Rule followed in each bond \[\left( Q-R \right)\times 3\text{ }=\text{ }P\] Hence, \[\left( Q-3 \right)\times 3=93\] \[\Rightarrow \left( Q-3 \right)=93\div 3\] \[Q-3=31\] \[\Rightarrow Q=31+3=34.\]
