Answers:

1. 3

1 + 5 = 6, 6 + 7 = 13, 13 + 9 = 22, ...

2. 5

There are two series,
S1 = 8 + 1 = 9, 9 + 2 = 11, 11 + 3 = 14, ...
S2 = 8 + 1 = 9, 9 + 1 = 10, 10 + 1 = 11, ...

3. 2

The series is:
3 × 1 + 2 = 5
5 × 2 + 3 = 13
13 × 3 + 4 = 43
43 × 4 + 5 = 177
177 × 5 + 6 = 891
891 × 6 + 7 = 5353

4. 3

There are two series:
S1 = 5 × 2 = 10, 10 × 2 = 20, 20 × 2 = 40 ...
S2 = 10 + 0 = 10, 10 + 0 = 10, 10 + 0 ...

5. 2

6 × 2 - 3 = 9, 9 × 2 - 5 = 13,
13 × 2 - 7 = 19, ...

6. 3

Let CP = x

SP = y

So, (y - x)/x * 100 = 50
y = 3x/2
3x/2 - 80 = x
x = 160

7. 3; Distance travelled = Perimeter

8. 5; 5 consonant + 4 vowel  5! × 4!

9. 5;



10. 4;
