If P denotes ‘+’, Q denotes ‘×’, R denotes ‘–’ and S denotes ‘÷’, then what is the value of 3 Q 5 P 4 R 15 S 5?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 16
Replace each letter by its sign, then work it out by BODMAS (division and multiplication before addition and subtraction).
With the signs: 3 × 5 + 4 – 15 ÷ 5
\(3\times5=15\)
\(15\div5=3\)
\(15+4-3=16\)
