Which two numbers (not digits) should be interchanged to make the given equation correct?
12 × 3 – 4 ÷ 2 + 41 = 7

Correct option is A

Given:
12 × 3 – 4 ÷ 2 + 41 = 7
From the given options -
(a) 7 and 41 After interchanging the digit we get following equation -
12 × 3 – 4 ÷ 2 + 7 = 41
12 × 3 – 2 + 7 = 41
36 – 2 + 7 = 41
43 – 2 = 41
41 = 41
Correct answer is (a).
