A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Here
Qty A
\(\sqrt{75} - \sqrt{27}\)
=\(5\sqrt{3}\) - \(3\sqrt{3}\)
=\(2\sqrt{3}\)
nearly = 3.4 (since \(\sqrt{3}\) = 1.728)
Now for Qty B
\(\sqrt{10}\)
we know 9 is the nearest sq value to 10
so square root of 9 = 3
and so square root of 10 = nearly close to 3
Hence qty A> QTy B.
It will be benefit if we know the square root value atleast till 5
