3p < 51
hence, p < 51/3
or, p < 17
similarly, 5p>75
or, p> 75/5
or, p> 15
Therefore only integer between 15 and 17 is 16
hence, p < 51/3
or, p < 17
similarly, 5p>75
or, p> 75/5
or, p> 15
Therefore only integer between 15 and 17 is 16

Given,
3p < 51
p < 17
again
5p > 75
p > 15.
So, 15 < p < 17.
p = 16
The best answer is B.
