If P means plus, M means minus, N means multiply and S means divide, then find the value of:
18 M 6 N 24 S 8 P 17
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 17
Each letter is replaced by its operation, and the expression is then worked out by BODMAS: division and multiplication before addition and subtraction.
18 M 6 N 24 S 8 P 17 becomes \(18-6\times24\div8+17\)
Division first: \(24\div8=3\)
Multiplication next: \(6\times3=18\)
Then \(18-18+17=17\)
Tip: Working from left to right, \((18-6)\times24\div8+17=53\), which is Option (2). Replace the letters first, then apply BODMAS; never work these expressions left to right.
