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? 22 B 5 D 12 A 4 C 6=?
112
111
114
113
113
Apply BODMAS/PEMDAS: Convert all letters to their respective operations first (A=/, B=*, C=+, D=-), then solve the sequence strictly from left to right following priority rules.
Apply BODMAS/PEMDAS: Convert all letters to their respective operations first (A=/, B=*, C=+, D=-), then solve the sequence strictly from left to right following priority rules.
Substitute Symbols with Operators
Replace the letters with their mathematical equivalents: 'A' = '/', 'B' = '*', 'C' = '+', 'D' = '-'. The equation becomes: 22 * 5 - 12 / 4 + 6 =?
Apply BODMAS Order
According to BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction), perform division first: 12 / 4 = 3. The equation is now: 22 * 5 - 3 + 6.
Perform Multiplication and Final Arithmetic
Next, perform multiplication: 22 * 5 = 110. Then perform addition and subtraction: 110 - 3 + 6 = 107 + 6 = 113.
A: 112 is incorrect based on the calculated result. B: 111 is mathematically incorrect. C: 114 is incorrect based on the sequence operations.
D is correct because the step-by-step evaluation using BODMAS rules (22 * 5 - 3 + 6) correctly yields 113.
In competitive exams, always ensure you follow the BODMAS hierarchy. Beginners often make mistakes by solving the equation linearly from left to right instead of prioritizing Division and Multiplication first.
