If ‘A’ denotes ‘addition’, ‘B’ denotes ‘multiplication’, ‘C’ denotes ‘subtraction’, and ‘D’ denotes ‘division’, then what will be the value of the following expression?
441 D 7 A 21 B 6 C (189 D 7) A (46 C 12)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 196.
Given equation: 441 D 7 A 21 B 6 C (189 D 7) A (46 C 12)
Given conditions: A ⇒ +; B ⇒ ×; C ⇒ -; D ⇒ ÷
After replacing the expression becomes:
= 441 ÷ 7 + 21 × 6 - (189 ÷ 7) + (46 - 12)
= 441 ÷ 7 + 21 × 6 - 27 + 34
= 63 + 21 × 6 - 27 + 34
= 63 + 126 - 27 + 34 = 196
