Question

If $3+9=31;15+12=45;18+9=36,$ Then $12+27=?$

Answer 1

Find the value of the expression

As given in the question:

$3+9=31;15+12=45;18+9=36,$ then to solve divide each number is divided by 3 and the quotients are written in the reverse order.

$$\begin{gathered} \frac{3}{3}+\frac{9}{3}=13\Rightarrow 31 \\ \frac{15}{3}+\frac{12}{3}=54\Rightarrow 45 \\ \frac{18}{3}+\frac{9}{3}=63\Rightarrow 36 \\ \therefore \frac{12}{3}+\frac{27}{3}=49\Rightarrow 94 \end{gathered}$$

Hence,$12+27=94$
