Question:

Which two numbers, from amongst the given options, should be interchanged to make the given equation correct?

14 + 39 − ($\sqrt{144}$ ÷ 4) + (5 × 3) − 6 = 63

Options:

14 and 6

5 and 39

4 and 3

4 and 6

Correct Answer:

4 and 3

Explanation:

14 + 39 − ($\sqrt{144}$ ÷ 4) + (5 × 3) − 6 = 63

After interchange 4 and 3

14 + 39 - ($\sqrt{144}$ ÷ 3 ) + (5 × 4) − 6

Apply BODMAS

14 + 39 - 12 ÷ 3 + (5 × 4) − 6

14 + 39 - 4 + (5 × 4) − 6

14 + 39 - 4 + 20 - 6

73 - 10

63
