Marks: +1, -0
[124(48÷6+4×3(6))]=[124 - {(48 ÷ 6 + 4 × 3 - (-6))}] =
Solution:  
Concept:
Order of Operations (BODMAS/PEMDAS) for simplifying mathematical expressions.
Explanation:
To solve this, we follow the BODMAS rule, which stands for Brackets, Orders (powers and roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).
Step 1: Simplify the expression inside the innermost bracket first.
We have 48÷6+4×3(6)48 ÷ 6 + 4 × 3 - (-6).
First, perform division and multiplication: 48÷6=848 ÷ 6 = 8 and 4×3=124 × 3 = 12.
So, the expression becomes 8+12(6)8 + 12 - (-6).
Next, handle the subtraction of a negative number, which is equivalent to addition: (6)=+6-(-6) = +6.
The expression is now 8+12+68 + 12 + 6.
Perform addition: 8+12=208 + 12 = 20, and 20+6=2620 + 6 = 26.
So, the value inside the curly bracket is 2626.
Step 2: Now substitute this value back into the main expression.
We have [12426][124 - {26}].
Step 3: Perform the subtraction.
12426=98124 - 26 = 98.
Answer:
98
The correct option is C.
