√4/√3 - √3/√4
= 2/√3 - √3/2
= (4 - 3)/2√3
= 1/2√3Correct Option: A
√4/√3 - √3/√4
= 2/√3 - √3/2
= (4 - 3)/2√3
= 1/2√3

√2/9
= √2/√9
= √2/3
= 1.4142/3Correct Option: B
√2/9
= √2/√9
= √2/3
= 1.4142/3
∴ 1/√2/9 = 0.4714

1/√3 = 1/√3 x (√3 / √3)
= √3/3
= 1.732 / 3Correct Option: C
1/√3 = 1/√3 x (√3 / √3)
= √3/3
= 1.732 / 3
= 0.577

Let x/ √2.25
= 550.
Then, x/1.5 = 550
∴ x = (550 x 1.5)
= (550 x 15/10) = 825Correct Option: A
Let N / √2.25 = 550.
Then, N / 1.5 = 550
∴ N = (550 x 1.5)
= (550 x 15) /10
= 825
