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%
