IMO, the correct answer is A

One needs to be clear with common square values to answer under 2 mins.

1)\((\sqrt{82}-1.7^2) / \sqrt{34}\)

now, we know 9 X 9 = 81 so, \(\sqrt{82}\) will be slightly greater than 9

Further, 17 X 17 = 289 so, \(1.7^2 = 2.89\)

Without getting into decimals we can simply do ---> 9-3=6

Now, we know 6 X 6 = 36

So, \(\sqrt{34}\) will be slightly less than 6

Finally, we can say \(\frac{6}{something less than 6}\) will always be > 1

Hence, 1 is true.



2. \(\frac{9978.4−0.0083}{101^2}\)

100 X 100 = 10000

Now, since 0.0083 is so small we can simply ignore it and the fraction will remain to be

\(\frac{9978.4}{10000}\)

It is clear that value will be something 0.99xxxx

so, definitely less than 1


3.\(\sqrt{143} X 7^{1/3} / 24.034\)
Now, 12 X 12 = 144, so the value \(\sqrt{143}\) of will be slightly less than 12

2^3 =8, so the value of \(7^{1/3}\) will be slightly less than 2

Now, even if we take 11.99 X 1.99 it will always be less than the denominator i.e 24.034

Hence, it is less than 1
