Question

PLEASE HELP!!!!!!!!!!!!!!!!!!

Answer 1

Option C
`(√(120))`

Explanation:

The easiest method is to find the number closest to the square of 11 i.e. 121. From all the options , ignore the square root , just find out the number

nearest to 121 ; we'll come to that 120 is very close to 121. So,
`√(120)` is the correct answer.

Let's verify all the options.

`√(118) = 10.8627804912 = 10.86(appx)`

`√(115) = 10.7238052948 = 10.72(appx)`

`√(120) = 10.9544511501 = 10.95(appx)`

`√(123) = 11.0905365064 = 11.09(appx)`

After verifying the values of all the options , 10.95 (appx value of
`√(120)`) is very close to 11.
