If + means -, - means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
64 × 8 ÷ 24 - 5 + 3
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 125.
Given conditions: + means -, - means ×, × means ÷, and ÷ means +
Given equation: 64 × 8 ÷ 24 - 5 + 3
After interchanging the expression becomes:
= (64 ÷ 8) + 24 × 5 - 3
= 8 + (24 × 5) - 3
= (8 + 120) - 3
= 128 - 3
= 125
Hence, 125 is the correct answer.
