Find the value of 18 – [6 – {4 – (8 + 3)}] 

Correct option is C

Let's solve step by step, following the order of operations (BODMAS rule).

Given expression:

18 – [6 – {4 – (8 + 3)}]

Step 1: Solve inside the parentheses

8 + 3 = 11

Now the expression becomes:18 – [6 – {4 – 11}]

Step 2: Solve inside the curly brackets

4 – 11 = -7

Now the expression becomes:18 – [6 – (-7)]

Step 3: Simplify inside the square brackets

Since subtracting a negative number is the same as adding:6 + 7 = 13

Now the expression becomes:18 – 13

Step 4: Final subtraction

18 – 13 = 5

Thus, the correct answer is (C) 5.
