Option C

10

Solution :

To find the value of the given expression, we follow the order of operations, often remembered by the acronym BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction).

The given expression is:
5 + [ 6 + ( 3 + 5 ) ÷ 2 ] ÷ 2

Step 1: Solve the innermost parentheses first
First, we calculate the sum inside the round brackets, which is:
3 + 5 = 8
Substituting this value back into the expression, we get:
5 + [ 6 + 8 ÷ 2 ] ÷ 2

Step 2: Solve the operations inside the square brackets
Inside the square brackets [ 6 + 8 ÷ 2 ] , we perform the division before the addition:
8 ÷ 2 = 4
Now the expression inside the square brackets becomes:
6 + 4 = 10
Substituting this value back into the main expression, we obtain:
5 + 10 ÷ 2

Step 3: Solve the remaining operations
In the expression 5 + 10 ÷ 2 , division has a higher priority than addition:
10 ÷ 2 = 5
Finally, perform the addition:
5 + 5 = 10

Thus, the expression evaluates to 10.
