Solution
1.The series is: 13
13 × 1 + 0 = 13
13 × 2 + 1 = 27
27 × 3 + 2 = 83
83 × 4 + 3 = 335
335 × 5 + 4 = 1679,...

2.The series is: 23
23 × 1  ̶  8 = 15
15 × 2  ̶  8 = 22
22 × 3  ̶  8 = 58
58 × 4  ̶  8 = 224
224 × 5  ̶  8 = 1112

3.The series is: 541
(541 ̶ 3)/2 = 269
(269 ̶ 3)/2 = 133
(133 ̶ 3)/2 = 65
(65 ̶ 3)/2 = 31
(31 ̶ 3)/2 = 14

4.The series is: 28
28 × (0.5) + 2 = 16
16 × (1.5) + 4 = 28
28 × (2.5) + 6 = 76
76 × (3.5) + 8 = 274
274 × (4.5) + 10 = 1243

5.The series is: 4
4 × 1 + 1 × 7 = 11
11 × 2 + 2 × 7 = 36
36 × 3 + 3 × 7 = 129
129 × 4 + 4 × 7 = 544
544 × 5 + 5 × 7 = 2755

6.Total number of buildings constructed across the state in the year 2001 is
= 1500 + 1250 + 1480 + 1724 + 1020 + 1136 = 8110
similarly, in 2003
= 1610 + 1320 + 1545 + 1800 + 1100 + 1230 = 8605
Reqd % = (8110/8605) × 100 = 94.24% ≈ 94%

7.Total buildings constructed in Town Mumbai over the given years
= 1250 + 1284 + 1320 + 1335 + 1396 + 1400 + 1450 = 9435

8.Reqd % = [(1800 ̶ 1750)/1750] × 100 = 2.85%

9.Difference = (1280 + 1175)  ̶  (1190 + 1050)
= 215

10.Reqd% = (1640/1880)× 100 = 87.23%
