33. 

A bird shooter was askgd how many birds he had in the bag. He replied that there were all sparrows but six, all pigeons but six, and all ducks but six. How many birds he had in the bag in all?

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

Answer: Option A

Explanation:

There were all sparrows but six' means that six birds were not sparrows but only pigeons and ducks.

Similarly, number of sparrows + number of ducks = 6 and number of sparrows + number of pigeons = 6.

This is possible when there are 3 sparrows, 3 pigeons and 3 ducks i.e. 9 birds in all.

Let total number of birds = x. let no. of sparrows = s, pigeons = p, ducks = d.
Given s = x-6. d = x-6. p = x-6.

s+d+p = x = 3x-18.
So x = 9.

There are 9 birds in all.

All sparrow but 6 are not sparrows = 6 = p+d.

All sparrow but 6 are not pigeons = 6 = s+d.

All sparrow but 6 are not ducks = 6 = p+s.

So total birds are = 6+6+6 = 18.

i.e p+d+s+d+p+s = 18.

= 2(p+d+s) = 18.

P+d+s = 9.

i.e possibility of 9 in equality is 3=p, 3=d, 3=s.

Let total number of birds = x.
Let no of sparrows = s, pigeons = p, ducks = d.
Given s = x - 6. d = x - 6. p = x - 6.
s + d + p = x = 3x - 18.
So x = 9.

There are 9 birds in all.

Let a total number of birds = x.
Let no of sparrows = s, pigeons = p, ducks = d.
Given s = x - 6. d = x - 6. p = x - 6.
s + d + p = x = 3x - 18.
So x = 9.

I am not understanding this. Please, anyone explain this.

This sentence "all sparrows but six" it simply means that " all sparrows but six are other birds"

So number of sparrows will be,
S = total -6;
P = total-6;
D = total-6;
S+P+D = total.
So by solving we get,
Total = 9 birds.
