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?
13 C 27 A 3 B 8 D 12 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 73.
Given the equation: 13 C 27 A 3 B 8 D 12 =?
Given conditions: 'A' stands for '÷', 'B' stands for '×', 'C' stands for '+', and 'D' stands for '-'
After interchanging the expression becomes:
= 13 + (27 ÷ 3) × 8 - 12
= 13 + (9 × 8) - 12
= 13 + 72 - 12
= 85 - 12
= 73
