If + means −, − means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
5 ÷ 5 + 5 – 10 × 10 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 5.
Given equation: 5 ÷ 5 + 5 – 10 × 10 = ?
Given conditions: + means −, − means ×, × means ÷, and ÷ means +
After interchanging the expression becomes:
= 5 + 5 - 5 × 10 ÷ 10
= 5 + 5 - 5 × 1
= 5 + 5 - 5
= 5
