Correct option is A
Given: 286 ÷ 13 × 2 + 50 - 6 = 0
As per the question- interchanging the sing + and – we get following equation-
286 ÷ 13 × 2 - 50 + 6 = 0
Explanation:
Following the BODMAS rule (Bracket, Orders (i.e. powers and square roots, etc.), Division and Multiplication, Addition and Subtraction):
1. Division (÷): 22 × 2 - 50 + 6
2. Multiplication (×): 44 – 50 + 6
3. Addition (+): 50 - 50
4. Subtraction (-): 0
Correct answer is (a) + and -.
