If A means Addition, B means Division, C means Multiplication and D means Subtraction. Then find the value of 49B7D9A15C6 = ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 88
Each letter is replaced by the operation it stands for, and the expression is then worked out by the BODMAS order: division and multiplication first, then addition and subtraction.
With B = ÷, D = −, A = + and C = ×: \(49\div7-9+15\times6\)
Division and multiplication first: \(7-9+90\)
\(=88\)
