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?
36 B 8 A 56 C 49 D 53=?
- A53
- B82
- C46
- D30
Solution & Step-by-step Explanation
To solve the equation, replace the letter codes with their respective mathematical operators:
A→÷
B→−
C→×
D→+
Substituting these into the given expression:
36−8÷56×49+53
Now, apply the BODMAS rule (Division, Multiplication, Addition, Subtraction):
Division:
8÷56=
