Which two signs need to be interchanged to make the following equation correct?
3 + 3 × 3 – 3 ÷ 3 = 3

Correct option is B

Given: 3 + 3 × 3 – 3 ÷ 3 = 3
From the given option-
(a) × and + after changing the sign we get following equation-
3 × 3 + 3 – 3 ÷ 3 = 3
3 × 3 + 3 – 1 = 3
9 + 3 – 1 = 3
12 – 1 = 3
11 ≠ 3
(b) + and ÷ after changing the sign we get following equation-
3 ÷ 3 × 3 – 3 + 3 = 3
1 × 3 – 3 + 3 = 3
3 – 3 + 3 = 3
6 – 3 = 3
3 = 3
Correct answer is (b) + and ÷
