1).The series is 93, 113, 133, 153, 173, ...
Hence, there should be 2197 in place of 2497.
Answer: d)
2).The series is 8 + 1.5 = 9.5, 9.5 + 2 = 11.5, 11.5 + 2.5 = 14, 14 + 3 = 17
Hence, there should be 9.5 in place of 8.5.
Answer: b)
3).The series is 5 × 1 + 2 = 7, 6 × 2 + 4 = 16, 7 × 3 + 6 = 27, 8 × 4 + 8 = 40, 9 × 5 + 10 = 55.
Hence, there should be 55 in place of 46.
Alternate Method: +9, +11, +13, +15 ...
Answer: e)
4).The series is +339, +678, +1356, +2712, ...
Hence, there should be 5524 in place of 5624.
Answer: a)
5).The series is 92 – 1, 112 – 2, 132 – 3, 152 – 4, 172 – 5, ...
Hence, there should be 284 in place of 223.
Answer: c)
6).Population of Muslims = 20 + 27.5 + 32.5 + 20 + 15 + 20 = 135 lakh
Population of Christians = 30 + 25 + 20 + 25 + 10 + 27.5 = 137.5 lakh
Population of Other religions = 25 + 20 + 27.5 + 10 + 27.5 + 32.5 = 142.5 lakh
Hence, population of Other religions is the maximum.
Answer: b)
7).Density = Population / Land (in km)2
Population density of China
= (20 + 30 + 25) / 50 × 16 / 100 = 9.375 persons per km
Population density of Turkey
= (27.5 + 25 + 20) / 50 × 25 / 100 = 5.8 persons per km
Population density of Norway
= (32.5 + 20 + 27.5) / 50 × 6 /100 = 26.67 persons per km
Population density of Spain
= (20 + 25 + 10) / 50 × 20 / 100 = 5.5 persons per km
Population density of Japan
= (15 + 10 + 27.5) / 50 × 18 / 100 = 5.83 persons per km
Population density of Iraq
= (20 + 27.5 + 32.5) / 50 × 5 /100 = 32 persons per km
In Spain, the population density is the minimum.
Answer: d)

Answer: e)
10).Muslim population of Iraq 2 years ago = 20 × 100 / 80 × 100 /80 = 31.25 lakh
Population of Christians 2 years ago = 27.5 × 100 / 50 × 100 / 50 = 110 lakh
Population of Others 2 years ago = 32.5 × 100 / 50 × 100 / 50 = 130 lakh
Total population of Iraq 2 years ago = 31.25 + 110 + 130 = 271.25 lakh
