  • A. 18 and 24
  • B. 7 and 18
  • C. 3 and 7
  • D. 72 and 24
Correct Answer: Option A - On interchanging the numbers from option (a) in the given equation ‘7 + 24 x 3 – 72 ÷ 18 = 58’ 7 + 18 x 3 – 72 ÷ 24 = 58 7 + 54 – 3 = 58 61 – 3 = 58 58 = 58 (L.H.S. = R.H.S.)
A. On interchanging the numbers from option (a) in the given equation ‘7 + 24 x 3 – 72 ÷ 18 = 58’ 7 + 18 x 3 – 72 ÷ 24 = 58 7 + 54 – 3 = 58 61 – 3 = 58 58 = 58 (L.H.S. = R.H.S.)

Explanations:

On interchanging the numbers from option (a) in the given equation ‘7 + 24 x 3 – 72 ÷ 18 = 58’ 7 + 18 x 3 – 72 ÷ 24 = 58 7 + 54 – 3 = 58 61 – 3 = 58 58 = 58 (L.H.S. = R.H.S.)
