If + means −, − means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
20 ÷ 2 + 4 – 8 × 4 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 148.
Given equation: 20 ÷ 2 + 4 - 8 × 4 = ?
Given conditions:
+ means −, − means ×, × means ÷, and ÷ means +
After interchanging the expression becomes:
= 20 + 2 - 4 × 8 ÷ 4
= 20 + 2 - 4 × 2
= 20 + 2 - 8
= 22 - 8
= 14
Hence, option 1 is the correct answer.
