Which two numbers (not digits) should be interchanged to make the given equation correct?
19 + 125 ÷ 25 – 100 ÷ 5 + 4 × 3 = 52
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 25 and 5
Given equation: 19 + 125 ÷ 25 – 100 ÷ 5 + 4 × 3 = 52
Option 3) 25 and 5
After two numbers (not digits) interchanged:
19 + (125 ÷ 5) – (100 ÷ 25) + 4 × 3 = 52
19 + 25 – 4 + (4 × 3) = 52
19 + 25 - 4 + 12 = 52
56 - 4 = 52
52 = 52
