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?
27 B 7 D 39 A 3 C 47 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 223.
27 B 7 D 39 A 3 C 47 = ?
After interchanging signs,
= 27 × 7 - (39 ÷ 3) + 47
= 189 - 13 + 47
= 176 + 47 = 223
