C+W=19
2C-1W=32

=> D.17

i will go for E. 13

i chose 13 since it is the least number in the list.

13 * 3 - 6 = 33 which is above 32

so Ans 13

3n - (19-n) > 32
n > 12.525

so the possible minimum value of n has to be 13.

E = 13

x = number of wrong questions
19*3 - 4x = 33(Since the question asks for minimum number above >32)
4x = 24, x = 6
