Which two numbers should be interchanged to make the given equation correct?
120 ÷ 12 x 6 + 24 - 15 = 27
Answer & explanation
Correct answer: option 3
By interchanging 12 and 24 in the equation:
120 ÷ 12 x 6 + 24 - 15 = 27, the equation becomes
120 ÷ 24 x 6 + 12 - 15 = 27
Using BODMAS rule,
⇒ 5 x 6 + 12 - 15 = 27
⇒ 30 + 12 - 15 = 27
LHS = RHS
The equation becomes correct.
