If ÷ means -, - means ×, × means +, + means ÷, what will come in place of the question mark (?)?
132 + 6 - 9 × 13 ÷ 31 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 180.
Given conditions: ÷ means -, - means ×, × means +, + means ÷
Given equation: 1132 + 6 - 9 × 13 ÷ 31 = ?
After interchanging the expression becomes:
(132 ÷ 6) × 9 + 13 - 31 =?
= (22 × 9) + 13 - 31
= (198 + 13) - 31
= 211 - 31
= 180
Hence, 180 is the correct answer.
