If ‘A’ denotes ‘addition’, ‘B’ denotes ‘multiplication’, ‘C’ denotes ‘subtraction’, and ‘D’ denotes ‘division’, then what will be the value of the following expression?
100 D (1 B 4) A 2 B (13 A 11) C 3 B (17 C 12)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 58.
Given equation: 100 D (1 B 4) A 2 B (13 A 11) C 3 B (17 C 12)
Given conditions: A ⇒ +; B ⇒ ×; C ⇒ -; D ⇒ ÷
After replacing the expression becomes:
= 100 ÷ (1 × 4) + 2 × (13 + 11) - 3 × (17 - 12)
= 100 ÷ 4 + 2 × 24 - 3 × 5
= 25 + 2 × 24 - 3 × 5
= 58
Hence, option 2 is the correct answer.
