Which two numbers should be interchanged to make the given equation correct?
4 × 8 - 12 + 5 = 16
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8 and 5.
Given equation: 4 × 8 - 12 + 5 = 16
Now, checking options one by one,
Option (1): 8 and 5 →
After interchanging the numbers we get;
⇒ 4 × 5 - 12 + 8 = 16
⇒ 20 - 12 + 8 = 16
⇒ 28 - 12 = 16
⇒ 16 = 16
Thus, by interchanging 8 and 5 the equation becomes correct so, there is need to check the other options.
Hence, the correct answer is 8 and 5.
