If ‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘–’ and ‘D’ denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
71 A 3 B 2 C 6 B (65 D 13) C 7 B4 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 19.
The given equation is: 71 A 3 B 2 C 6 B (65 D 13) C 7 B4
‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘–’ and ‘D’ denotes ‘÷’.
By replacing the letters with their corresponding signs,
71 + 3 × 2 – 6 × (65 ÷ 13) – 7 × 4
= 71 + 6 – 6 × (5) – 7 × 4
= 71 + 6 – 30 – 28
= 77 – 58
= 19
Hence, option 2 is the correct option.
