If you post a problem, remember you are asking for help. I get put off when you say, "you must show your working," first because I do not in fact have to do it at all, and second, it's bad English.
So, rather than just doing a copy and paste, edit it so it looks like you're requesting assistance.
So, on to the problem:
240 lambs were born
80% of sheep had lambs, so there were 240/.8 = 300 sheep in the flock
That answers the question.
If you are interested in how many had 1,2,3 lambs, then
30% of 240 = 72 had 1 lamb
40% of 240 = 96 had 2 lambs
That leaves 30% = 72 had 3 lambs
