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?
83 C 7 B 539 A 49 D 29 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 131.
Given equation: 83 C 7 B 539 A 49 D 29 = ?
After replacing the letters with signs;
83 + 7 × (539 ÷ 49) - 29 = ?
= 83 + (7 × 11) - 29
= (83 + 77) - 29
= 160 - 29
= 131
