If A denotes ‘+', B denotes '×', C denotes ‘-’, and D denotes ' \(\div\) ', then what will be the value of the following expression? 144 C 8 B 20 A 81 D 3 = ?
Given:
144 C 8 B 20 A 81 D 3 = ?
Using the BODMAS rule:
The given letters represent the following arithmetic operations:
| Letter | Symbol |
|---|---|
| A | + |
| B | × |
| C | - |
| D | \(\div\) |
On substituting the operations in the equation,
⇒ 144 - 8 × 20 +81 ÷ 3
⇒ 144 - 8 × 20 + 27
⇒ 144 + 27 - 160
⇒ 171 - 160
⇒ 11
Thus, the correct answer is 'Option 2)' .
