Which two numbers should be interchanged to make the given equation correct?
8 × (7 + 5 − 3) + (46 ÷ 23) × 6 − 69 = 44
(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: C
Explanation
The correct answer is option 3 i.e. 46 and 69.
8 × (7 + 5 − 3) + (46 ÷ 23) × 6 − 69 = 44
After interchanging numbers,
8 × (7 + 5 − 3) + (69 ÷ 23) × 6 − 46 = 44
8 × 9 + 18 - 46 = 44
72 + 18 - 46 = 44
90 - 46 = 44
44 = 44
