Question Stem:
Pigs + Cows = 40
Stmt I
There could be various possible answers to this statement
pigs = 10, cows = 30
pigs = 11, cows = 29
pigs = 1, cow = 39
Insufficient
Stmt II
farm has more than 12 pigs. it could be 13,14,15,16..... So we cannot be certain how many pigs or how many cows are there in the farm
Insufficient
Stmt I & II
the only value that satisfies both statements is 13 pigs and 27 cows.
sufficient
C

@sacx
The Q stem says 2/3 or 40 is the number of either cows or pigs,
not the total of pigs and cow, which u have assumed.
So, your reasoning is not correct
From A: if cows>2(pigs),
then there are 2 options.
cows = 3*pigs, which means cows = 45, pigs =15
OR
cows = 4*pigs which means cows = 48, pigs =12
OR
cows = 5 * pigs, which means cows = 50, pigs =10
No concrete answer
So, insufficient
From B: nothing can be deduced about the no. of cows
Combining both,
pigs can be 15, then cows = 45
Hence, C is the answer.
Cheers

According to you, if 40 is the number of pigs or cows, then why number of cows is 45?? and number of pigs is 15? Just trying to understand...anshulseth wrote:@sacx
