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)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 69 and 48.
69 + 15 − (14 × 4) ÷ 2 + (48 ÷ 3) = 58
On interchanging numbers,
48 + 15 − (14 × 4 ) ÷ 2 + (69 ÷ 3) = 58
63 - (56 ÷ 2) + 23 = 58
63 - 28 + 23 = 58
58 = 58
