If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will come in place of the question mark (?) in the following equation?
455 A 5 D 17 C 36 B 4 = ?
Correct Answer :
218
Solution :
The correct answer is 218.
We are given the values for each letter in the equation as follows:
‘A’ stands for ‘÷’ (Division)
‘B’ stands for ‘×’ (Multiplication)
‘C’ stands for ‘+’ (Addition)
‘D’ stands for ‘−’ (Subtraction)
The given equation to solve is:
455 A 5 D 17 C 36 B 4 = ?
Substituting the given operations into the equation, we obtain:
455 ÷ 5 − 17 + 36 × 4
Following the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction), we solve step-by-step:
Step 1: Perform Division
455 ÷ 5 = 91
The equation becomes:
91 − 17 + 36 × 4
Step 2: Perform Multiplication
36 × 4 = 144
The equation becomes:
91 − 17 + 144
Step 3: Perform Subtraction and Addition from left to right
91 − 17 = 74
74 + 144 = 218
Therefore, the value that replaces the question mark (?) is 218.
