Q:
A) 8 | B) 18 |
C) 9 | D) 10 |
Answer: C) 9

Explanation:
There were all parrots but six means that six birds were not parrots but only pigeons and koels.
Similarly, number of parrots + number of koels = 6 and number of parrots + number of pigeons = 6.
This is possible when there are 3 parrots, 3 pigeons and 3 koels i.e. 9 birds in all.
