If Q means 'add', J means 'multiply by', T means 'subtract' and K means 'divide by', then 30 K 2 Q 3 J 6 T 5 = ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 28
Each letter is first replaced by the operation it stands for (Q = +, J = ×, T = −, K = ÷), and the expression is then worked out by BODMAS: division and multiplication before addition and subtraction.
30 K 2 Q 3 J 6 T 5 becomes \(30\div2+3\times6-5\)
\(=15+18-5\)
\(=28\)
