If 'A' denotes 'addition', 'B' denotes 'multiplication', 'C' denotes 'subtraction', and 'D' denotes 'division', then what will be the value of the following expression?
74 A (31 B 2 ) B 2 C ( 68 C 4 ) D ( 4 B 2) = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 190.
Given equation: 74 A (31 B 2 ) B 2 C ( 68 C 4 ) D ( 4 B 2) = ?
Given condition: 'A' → '+', 'B' → '×', 'C' → '-', and 'D' → '÷'
After substituting the equation becomes;
= 74 + (31 × 2 ) × 2 - ( 68 - 4 ) ÷ ( 4 × 2)
= 74 + 62 × 2 - 64 ÷ 8
= 74 + 62 × 2 - 8
= 74 + 124 - 8
= 190
Hence, option 2 is the correct answer.
