Which two numbers should be interchanged to make the given equation correct?
4 x 8 - 12 + 5 = 16
Answer & explanation
Correct answer: option 2
In the equation, 4 x 8 - 12 + 5 = 16
if we interchange 8 and 5, it becomes:
4 x 5 - 12 + 8 = 16
LHS = 4 x 5 - 12 + 8
= 20 - 12 + 8
= 16 = RHS
Thus, the interchange makes the equation correct.
