Statement 1 allows you to enter information in the column label Blue Eyes, but does not give any way to compare the brown an blue eyed wolves - INSUFFICIENT.
Statement 2 allows you to enter information in the column label Brown Eyes, but does not give any way to compare the brown an blue eyed wolves - INSUFFICIENT.
Brown Eyes Blue Eyes Total
White Coat 2y 4x
Grey Coat y 3x
Total 3y 7x 55
Possible combinations of x and y you can achieve from the ratios given in both statement are as follows:
x = 1 and y = 16
Blue Eyed = 7
Brown Eyed = 48
x = 4 and y = 9
Blue Eyed = 28
Brown Eyed = 27
x = 7 and y = 2
Blue Eyed = 49
Brown Eyed = 6
There are instances with more brown-eyed wolves and others with more blue-eyed wolves. Insufficient.
The answer is E
