Question
Find the missing number, if same rule is followed in all the three figures.
✓
Answer
(D): The rule followed is:
$ \begin{aligned} & (5 \times 2)+(3 \times 4)=10+12=22 ; \\ & (6 \times 4)+(2 \times 3)=24+6=30 \end{aligned} $
So, $(7 \times 3)+(5 \times 4)=21+20=41$
$ \begin{aligned} & (5 \times 2)+(3 \times 4)=10+12=22 ; \\ & (6 \times 4)+(2 \times 3)=24+6=30 \end{aligned} $
So, $(7 \times 3)+(5 \times 4)=21+20=41$
