Correct Answer: 6 + 8 x 2 - 7 = 0


Solution : We have to interchange + and -, 8 and 7, in all the options.

Option first: 8 - 7 + 3 x 5 = 35

8 + 7 - 3 x 5 = 33. Here, the equation is incorrect.

Option second: 7 x 8 + 6 - 9 = 25

8 x 7 - 6 + 9 = 41. Here, the equation is incorrect.

Option third: 6 + 8 x 2 - 7 = 0

6 - 7 x 2 + 8 = 0. Here, the equation is correct.

Option fourth: 8 x 2 + 7 - 6 = 9

7 x 2 - 8 + 6 = 0. Here, the equation is incorrect.

Hence, third option is correct.
