Your Answer
A
27
Correct Answer
B
24
Correct Answer
C
16
Correct Answer
D
19

Solution

The correct options are
B 24
C 16
D 19
Prime factorisation of 625 is 
625=5×5×5×5

So, 625=5×5––––×5×5––––
 625=5×5=25

Given: x < 625, which implies that 'y' can have values less than 25, as x = y2.

Hence, the options, 24, 16 and 19 are the possible values for 'y' as they are less than 25.
But first option is 27 and 27 > 25. So, 'y' cannot take the value 27.
