If L denotes ‘×’, M denotes ‘+’, P denotes ‘÷’ and Q denotes ‘–’, then what is the value of 72 P 12 M 8 Q 8 M 3 L 7?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 27
Replace each letter by its sign, then work it out by BODMAS (division and multiplication before addition and subtraction).
With the signs: 72 ÷ 12 + 8 – 8 + 3 × 7
\(72\div12=6\)
\(3\times7=21\)
\(6+8-8+21=27\)
