If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘–’, what will come in place of the question mark (?) in the following equation?
70 D 11 B 5 C 45 A 9 = ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 20.
70 D 11 B 5 C 45 A 9 = ?
After interchanging signs,
= 70 - 11 × 5 + (45 ÷ 9)
= 70 - 55 + 5 = 20.
