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?
74 A (17 C 2 B 24) D 2 A 16 C 3 B 8 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 119.
Given expression: 74 A (17 C 2 B 24) D 2 A 16 C 3 B 8 = ?
Replacing letters with the signs in the expression:
74 + (17 × 2 - 24) ÷ 2 + 16 × 3 - 8
= 74 + (34 - 24) ÷ 2 + 16 × 3 - 8
= 74 + 10 ÷ 2 + 16 × 3 - 8
= 74 + 5 + 16 × 3 - 8
= 74 + 5 + 48 - 8
= 127 - 8
= 119
Hence, the correct answer is "119".
