Which two numbers should be interchanged to make the given equation correct?
29 + 46 - (48 ÷ 4) + (7 × 3) - 26 = 61
(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: D
Explanation
The correct answer is option 4 i.e. 4 and 3.
Given equation: 29 + 46 - (48 ÷ 4) + (7 × 3) - 26 = 61
Option 4) 4 and 3
29 + 46 - (48 ÷ 3) + (7 × 4) - 26 = 61
29 + 46 - 16 + 28 - 26 = 61
103 - 42 = 61
61 = 61
