Q: Which two numbers should be interchanged in the following equation to make it correct? 12 x 2 + 8 – 48 ÷ 6 = 20
  • A. 2 and 6
  • B. 6 and 8
  • C. 8 and 12
  • D. 12 and 48
Correct Answer: Option C - The given equation- 12 x 2 + 8 – 48 ÷ 6 = 20 On interchanging the number 8 and 12 8 x 2 + 12 – 48 ÷ 6 = 20 16 + 12 – 8 = 20 28 – 8 = 20 20 = 20 L.H.S = R.H.S Hence option (c) is correct.
C. The given equation- 12 x 2 + 8 – 48 ÷ 6 = 20 On interchanging the number 8 and 12 8 x 2 + 12 – 48 ÷ 6 = 20 16 + 12 – 8 = 20 28 – 8 = 20 20 = 20 L.H.S = R.H.S Hence option (c) is correct.
