BODMAS=(Brackets,Orders,Division,Multiplication,Addition,Subtraction)
Focus on the bracket first: 4×6=24. Then divide 48/24=2. Finally, perform 10+8+6−2.
Performing the addition and subtraction before the division or failing to solve the bracket first (i.e., calculating 48/4×6 instead of 48/(4×6)).
Simplify the bracket
According to the BODMAS rule, first solve the expression inside the parentheses: (4×6)=24.
4×6=24
Perform division
Substitute the bracket result back into the expression: 10+8+6−48÷24. Then, perform the division operation: 48÷24=2.
48÷24=2
Perform addition and subtraction
Finally, solve the remaining additions and subtractions from left to right: 10+8+6−2=24−2=22.
10+8+6−2=22
B is correct because the result of the expression 10+8+6−48÷24 is 22.
Always remember the order of operations (BODMAS/PEMDAS) for all quantitative aptitude problems involving multiple operators, as it is a common source of negative marking in exams.
