If × means −, ÷ means +, − means ÷, and + means ×, then what will be the value of the following expression?
125 - 25 ÷ 4 + 25 × 4 + 10 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 65.
Given conditions: × means −, ÷ means +, − means ÷, and + means ×
Given equation: 125 - 25 ÷ 4 + 25 × 4 + 10 =?
After interchanging the expression becomes:
= 125 ÷ 25 + 4 × 25 − 4 × 10 =?
= 5 + 4 × 25 − 4 × 10
= 5 + 100 − 40
= 105 - 40
= 65
Hence, 65 is the correct answer.
