There are 5 ways to choose the required 1 boy.  Then, for each of those 5 ways, there are 4 ways to choose the required 1 girl.  Then for each of those 20 ways, there remain 7 people, so 7 ways to choose the third committee member, and finally 6 ways to choose the fourth committee member.  Altogether, 5 times 4 times 7 times 6.  You can do your own arithmetic.
