Certainly a venn diagram.

But this one is tricky. Instead of taking likes, make venn diagram with dislikes.

D

Let total = x
Dislike LB = 2x/3
Dislike LB and BS = 2x/5

Dislike LB and like BS = 2x/3 - 2x/5 = 4x/15

St1: total = 120 then we got the answer = 32: SUFF

St2: 40 + 2x/3 = x i.e x = 120. We got the answer = 32: SUFF

Consider a grid with the 4 sections
(L, ~L), (B, ~B) where L = likes Lima ~L= hate Lima
and similarly for B. Imagine a last column and row with the totals.

S1 : T = 120

Sufficient as we can calculate (~L, B) entry.

S2: Total who like Lima beans = 40
Sufficient as this gives T/3= 120

D.

1)

Students who dislike lima beans = 2/3 *120 = 80

Students who dislike lima beans and also brussel sprouts = 3/5 *80 = 48

hence students who dislike lima beans and like brussel sprouts = 80 - 48

Now if the question asked to find the number of persons who like brussel sprouts. then the above information would have been Insuff

2) Students who like lima beans = 40
=> 1/3 Students = 40
=. students =120

Now use the method used in 1)
