#1. T=120
L(D)=dislike lima beans = 2/3*120=80
B(D)=dislike B = 3/5*80=48. (i.e those who dislike both L and B)
We need to find those who dislike L i.e L(D) but like B.

So, we know that out of those who dislike L 3/5 dislike B which implies that out of those who dislike L, 2/5th like B which is what we want.
B(Like)=2/5(80)=32

Hence 1 is sufficient

#2. 1/3(total)=40
Hence we get the total as 120 so same as above and hence sufficient.

So ans. D.)
