The is between which two integers?

The correct answer is: 6 & 7

GIVEN-
given number = √40
TO FIND-
Numbers between which √40 lie.
SOLUTION-
We know that the nearest perfect square before and after 40 are 36 and 49, respectively.
Hence, √40 lies between √36 i.e. 6 and √49 i.e. 7.
From the given options, option b i.e. 4 & 5 are both <= 6, option d i.e. 5 & 6 are both <= 6 and option c i.e. 7 & 8 are both >= 7.
Hence, the correct option is option a i.e. 6 and 7.
FINAL ANSWER-
Option 'a' i.e. '6 & 7' is the correct answer to the given question.
