Q: Which two numbers should be interchanged to make the given equation correct? 69 + 15 − (14 × 4 ) ÷ 2 + (48 ÷ 3) = 58 (NOTE: Numbers must be interchanged and not the constituent digits e.g. if 2 and 3 are to be interchanged in the equation 43 × 3 + 4 ÷ 2, then interchanged equation is 43 × 2 + 4 ÷ 3)
  • A. 48 and 15
  • B. 4 and 2
  • C. 3 and 4
  • D. 69 and 48
Correct Answer: Option D - According to question, Given expression 69 + 15 - (14 x 4) ÷ 2 + (45÷3) = 58 From option (d), On interchanging the number, 48 + 15 - (14 x 4) ÷ 2 + (69 ÷3) = 58 63 - 28 + 23 = 58 58 = 58 ⇒ LHS = RHS Hence option (d) is correct.
