​

Answer 1

Answer:

3 students ke paas kuch bhi nhi.

Answer 2

Answer:

Number of students having cats = 14

Number of students having dogs = 10

Number of students having parrots = 5

Number of students having both cat and dog = 4

Number of students having both dog and parrot = 1

Number of students having both parrot and cat = 3

Total number of students having any pet = 14+10+5-(4+1+3)

= 29-8

= 21

Now, Number of students having none of the pets = 26-21

= 5

Ans = 5
