If "A", "B", "X", and "R" respectively denote "divided by", "added to", "subtracted from", and "multiplied by", then evaluate "18R12A4X8B6"

Question

If

• "A" denotes "divided by"
• "B" denotes "added to"
• "X" denotes "subtracted from"
• "R" denotes "multiplied by"

then $$18R12A4X8B6\;=\;\text{?}$$

$\left(A\right)50 \quad\left(B\right)102 \quad \left(C\right)45 \quad \left(D\right)32$

My Approach $\Longrightarrow$ I tried it in two ways

First approach: $$18\times\left[\left(8+6\right)-\left(12\div4\right)\right]=198$$

Second approach: $$18\times12\div4-8+6=40$$

Answer 1

18*12/4-8+6 =18*3-8+6 =54-8+6 =44+6 =50 Correct option is A
