Solution:
1). The differences are 1 - 0 = 1 = 13 ; 9 - 1 = 8= 23 ; 36 - 9 = 27 = 33 ; 99 – 36 = 63 ≠ 43 , but
100 - 36 = 64 = 43 ;
225 – 100 = 125 = 53 ;
441 – 225 = 216 = 63

2). The series is +5, +7, +9, +11, ....

3). The series is ×2.5, ×2 alternately

4). The series is ÷2, ÷1.5 alternately.

5). The series is an alternate series, having
S 1 = 2   5   14   41; ×3 – 1 in each term
S 2 = 3   8   23   69; ×3 – 1 in each term

6). The required average
= [6000 × 1/3 +6400 × 3/8 +10000 × +10200 × 1/3 +10600 × 1/2 +13000 × 6/13] ÷6
= [2000+2400+4000+3400+5300+6000] ÷ 6
= 23100/6 = 3850

7). Male - 2011 = 4400/11 × 8 = 3200
Female - 2016 = 10500/3 × 1 = 3500
Required per cent = 3500 – 3200/3200 × 100 = 9.375%

8). Male-Tamil - 2014 =10200/3 × 2 = 6800
Female-English - 2011 = 4400/11 × 3 = 1200
Ratio = 6800/1200 = 17/3 = 17: 3

9). Tamil - 2013 = 10000/5 × 2 = 4000
English - 2013 = 6300/9 × 2 = 1400
Required per cent = 1400/4000 × 100 = 35%
