Answer: Option 4 is correct.

Explanation:

Since we have given that


\frac{3.\bar{1}}{1}

so, Let x = 3.1111......... (1)

Now, multiply by 10, we get that

10x = 31.1111.............(2)

Now, subtract (2)-(1)


10x-x=31.1111...-3.1111............\\\\9x=28\\\\x=(28)/(9)

Hence, Option 4 is correct.
