If A denotes ‘addition’, B denotes ‘multiplication’, C denotes ‘subtraction’, and D denotes ‘division’, then what will be the value of the following expression?
(45 D 9) B 5 A 8 B (7 A 3 C 6) C (28 D (4 D 4))
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 29.
Given equation: (45 D 9) B 5 A 8 B (7 A 3 C 6) C (28 D (4 D 4))
Given conditions: A ⇒ +; B ⇒ ×; C ⇒ -; D ⇒ ÷
After replacing the expression becomes:
= (45 ÷ 9) × 5 + 8 × (7 + 3 - 6) - (28 ÷ (4 ÷ 4))
= 5 × 5 + 8 × 4 - 28 = 29
