Answer:  (4) 5 + 2 – 12 x 6 /2 = 10

Explanation:-
If ‘-‘ stands for addition, ‘+’ for multiplication, ‘/’ for subtraction and ‘x’ for division.

Taken option (1),
Put the value of signs  in the option (1),
Then, 5 – 2 x 12 /6 + 2 = 4
5 – 2 x 2 + 2
5 – 4 + 2
1 + 2  = 3
3 does not equal to 4.
Then, this option is not correct.

Taken option (2),
Put the value of signs  in the option (2),
Then, 5 x 2 + 12 – 6/2 = 13
10 + 12 – 3
22 – 3
 = 19
19 is does not equal to 13,
This option is not correct.

Taken option (3),
Put the value of signs  in the option,
Then, 5 + 2 x 12 /6 – 2 = 27
5 + 2 x 2 – 2
5 + 4 – 2
9 – 2
 = 7
7 does not equal to 27.
This option is also incorrect.

Taken option (4),
Put the value of signs  in the option,
Then, 5 x 2 + 12/6- 2 = 10
10 + 2 – 2
10 = 10 

Then, the option is correct.

Hence, the answer is (4) 5 + 2 – 12 x 6 /2 = 10
