Options

A. 9
B. 18
C. 27
D. 36

Answer

A

Explanation

According to the question, three statements are as follow:
.There were all sparrows but six..
This statement means that six birds were not sparrows but only pigeons and ducks i.e.
Number of pigeons + Number of ducks = 6 ... (i)
Similarly, there were all pigeons but six. means that six birds were not pigeons but only Sparrows and ducks i.e.
Number of Sparrows + Number of ducks = 6 ... (ii)
And there were all ducks but six. means that six birds were not ducks but only Sparrows and pigeons i.e.
Number of Sparrows + Number of pigeons = 6 ... (iii)
From equation (i), (ii) & (iii), it is clear that Number of sparrows=Number of pigeons=Number of ducks = 3 [each]
So, total number of birds in the bag = 3 + 3 + 3 = 9 birds.
