Answer:

3

Step-by-step explanation:

Considering the given equation

x = 55 + 10% of 600 - 120 ÷ (9.09% of 121 + 11.11% of 81)

x = 55 + 10% of 600 - 120 ÷ (11 + 9)

x = 55 + 10% of 600 - 120 ÷ 20

x = 55 + 10% of 600 - 6

x = 55 + 60 - 6

x = 115 - 6

x = 109

Now we need to see what from the given options can be added to x = 109 to make it a perfect square

109 + (-9) = 100

109 + 12 = 121

∴ Both -9 and 12 can be added to make it a perfect square.

∴ Option 3 is right answer.
