If + means -, - means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
2 ÷ 5 + 2 - 5 × 5 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 5.
Given conditions: + means -, - means ×, × means ÷, and ÷ means +
Given equation: 2 ÷ 5 + 2 - 5 × 5 = ?
After interchanging the expression becomes:
2 + 5 - 2 × (5 ÷ 5) = ?
= 2 + 5 - (2 × 1)
= (2 + 5) - 2
= 7 - 2
= 5
Hence, the correct answer is 5.
