Correct Answer - Option 3 : ÷ × + =
Option 1 :530 ÷ 2 + 3 - 5 = 800
Applying BODMAS rule
265 + 3 - 5 = 800
263 = 800
This is wrong.
Option 2 : 530 ÷ 2 - 3 - 5 = 800
265 -8 = 800
258 = 800
This is also wrong.
Option 3 : 530 ÷ 2 × 3 + 5 = 800
265 × 3 + 5 = 800
795 + 5 = 800
800 = 800
This is correct.
Hence, option 3 is the correct answer.
