If + means -, - means ×, × means ÷, and ÷ means +, what will be the value of the following expression?
65 ÷ 35 + 72 × 8 - 5
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 55.
Given conditions: + means -, - means ×, × means ÷, and ÷ means +
Given equation: 65 ÷ 35 + 72 × 8 - 5
After interchanging the expression becomes:
= 65 + 35 - (72 ÷ 8) × 5
= 65 + 35 - (9 × 5)
= (65 + 35) - 45
= 100 - 45
= 55
Hence, 55 is the correct answer.
