If A denotes ‘addition’, B denotes ‘multiplication’, C denotes ‘subtraction’, and D denotes
‘division’, then what will be the value of the following expression?
66 A (132 D 12) C (4 A 3) B (15 D 5) A 16 B (–3)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 8.
Given equation: 66 A (132 D 12) C (4 A 3) B (15 D 5) A 16 B (–3)
Given conditions: A ⇒ +; B ⇒ ×; C ⇒ -; D ⇒ ÷
After replacing the expression becomes:
= 66 + (132 ÷ 12) - (4 + 3) × (15 ÷ 5) + 16 × (–3)
= 66 + 11 - 7 × 3 + 16 × (–3)
= 66 + 11 - 21 - 48 = 8
