30 is the right answer and here is the working:
Sam's total friends are 300, out of which 25% are male. That means 300 x 25/100 = 75 are male friends.
She likes 40% of her male friends (for a moment disregard how she can have a friend whome she doesn't like!). That means
75 x 40 / 100 = 30
So, she likes 30 male friends.

Easy its 30. 25% of 300 is 75 and 40% of that is 30.

Number of male friends = 300*25% = 75
Number of female friends = 300 - 75 = 225
40% of her male friends = 75 * 40% = 30.

300 * 1/4* 2/5= 75/1 * 2/5= 30

300 friends, 1/4 are male, 4/10 she likes.
So 300*1/4*4/10
the 4's cancel out, so it becomes 300*1/10 = 30
