Like Popcorn Don't like Popcorn

Like Peanuts 300 ?
Don't like peanuts 500 B
---------------------------------------------------
1800 A 2000


Now as per Statement 1 :- A+B > 700 which does not say anything about ?
Statement 2 :- B >= 1200 which again does not confirm the number of people like peanuts

combining both statements again does not say anything about ?

Hence E should be the answer

Popcorn(only) + Peanuts(only) + Both + Neither = 2000 --- (1)
Popcorn(only) + Both = 800
Both = 300 --> Popcorn(only) = 800 - 300 = 500

N(Peanuts) = Peanuts(only) + Both = ?

St1: Neither >= 700. Since question asks atmost, fix the value of Neither to 700.
Substitute in (1) --> Peanuts(only) + Both = 2000 - (500 + 700) = 800.
Sufficient

St2: Popcorn(only) + Neither >= 1200
Popcorn(only) = 500 --> Neither >=700 --> Peanuts(only) <= 500

Since the question asks atmost(maximum) how many like peanuts, we have to fix the value of 'Neither' to minimum --> Neither = 700
Hence, Peanuts(only) + Both = 500 + 300 = 800
Sufficient

Hi,

we are looking for EXACT number but AT THE MOST..
so relook in your solution and you will find you both statements are sufficient

Both the statements are enough to find the MAXIMUM value, which is 800. The answer should be (D).

Can someone please explain how statement 2 adds additional info? The info provided in the q stem alone is sufficient to derive info provided in statement 2, is it not?

From the q stem alone (black : given info from q stem; red : info you can derive from q stem).

................. PopCorn...........Not PopCorn...... Total
Peanuts............300.........
Not Peanuts........500
Total...............800........... 1200..................2000

relations in 2 overlapping sets


when "neither" is maxed overlap is maxed and thus both is maxed and accordingly "only set A" and "only set B" are both minimised , and vice versa.

let Peanuts set = A and pop set = B and Peanuts only = a and Pop only = b

Total = a+b+both+neither

(a+b) = total -both -neither , total = 2000, both = 300, b= 500

thus a = 2000-500-300-neither and to max a we need min neither

from 1

neither min = 700 thus a = 500.... suff

from 2

min (b+neither ) = 1200 thus min neither is 1200-500 = 700 ... same info as in 1.... suff

Pop + Pea - Both + Neither = 2000
Both = 300
Pop = 800
=> Pea + Neither = 2000 + 300 - 800 = 1500

(1) At least 700 people do not like eating popcorn or peanuts.

--> Neither >= 700
--> 1500 - Pea >= 700
--> Pea =< 800

Max(Pea)=800
Suff.

(2) At least 1,200 people do not like eating peanuts.
--> Min (Pea) = 1200
Also, Max(Pea)= Max(1500 - Neither)= 1500 with Neither = 0

Suff.
So D is the answer.
