Answer :

1 ) 10 cats caught 10 rats in  10 sec
Then
1 cat  in 10 sec caught = 1 rat
1 cat  in 100 sec caught = 10 rats
So,
100 rats in 100 sec caught by 10 cats

So,
10 cats can caught 100 rats in 100 sec                          ( Ans )

2 ) Cube comprises square on all of its surface , In the same way square comprises line on all of its side .

SO,
Option C                      ( Ans )

3 ) 2  , 7  14  , 23  _____   47 
We can write it As :

2 
7 =  2 + 5
14 = 7 + 7
23 = 14 + 9
So
23 + 11 = 34
So,

2  , 7  14  , 23  , 34  , 47                       ( Option C )     ( Ans )

4 ) 4 , 6  , 12 , 14 , 28 , 30 , ____ 

4 
6 = 4 + 2
12 = 6 $\times$ 2
14 = 12 + 2
28 = 14 $\times$ 2
30 = 28 + 2
So next digit will be
60 = 30 $\times$ 2
So,

4 , 6  , 12 , 14 , 28 , 30 , 60          (  Option D  )  ( Ans )

5 ) 1 , 4 , 9 , 16 , 25  , ___
We can write it As:
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
So next digit will be
6² = 36

1 , 4 , 9 , 16 , 25  , 36                             ( Ans )

6 ) az  , by , cx  , ___
We can see that there are multiplication of alphbets as :
a , b , c from starting  , And z , y , x from last 
So,
Next term will be
dw
​SO,
az  , by , cx  , dw               ( Option D )           (Ans )
