If + means −, × means +, − means ÷, ÷ means ×, what will come in place of the question mark (?)?
89 × 36 – 9 + 2 ÷ 11 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 71.
Given equation: 89 × 36 – 9 + 2 ÷ 11 = ?
Given conditions:
+ means −, × means +, − means ÷, ÷ means ×
After interchanging the expression becomes:
= 89 + 36 ÷ 9 - 2 × 11
= 89 + 4 - 2 × 11
= 89 + 4 - 22
= 89 - 18
= 71
Hence, option 1 is the correct answer.
