Answers:

Directions (1-5):

1) Answer: a)

1290*(1/2) = 645

645*(2/3) = 430

430*(3/4) = 322.5

322.5*(4/5) = 258

258*(5/6) = 215

2) Answer: d)

The difference of difference is, 11, 13, 15, 17,…

3) Answer: b)

52 + 63 + 6 = 274

274 + 53 + 5 = 404

404 + 43 + 4 = 472

472 + 33 + 3 = 502

502 + 23 + 2 = 512

4) Answer: c)

1*2 = 22

22*3 = 66

66*5 = 330

330*7 = 2310

2310*11 = 25410

5) Answer: e)

126*0.5 + 13 = 64

64*1 + 23 = 72

72*2 + 33 = 171

171*4 +43 = 748

748*8 + 53 = 6109

Directions (6-10):

6) Answer: d)

The total female population in village A

= >80000*(9/20) = 36000

The total female population in village C

= >120000*(2/5) = 48000

Required ratio = 36000 : 48000 = 3 : 4

7) Answer: c)

Total population in village B and C together

= >90000 + 120000 = 210000

Total population in village D and E together

= >100000 + 150000 = 250000

Required % = (210000/250000)*100 = 84 %

8) Answer: a)

The total population in village A = 80000

The total male population in village B and E together

= >[90000*(2/5)] + [150000*(13/25)]

= >36000 + 78000 = 114000

Required difference = 114000 – 80000 = 34000

9) Answer: e)

The average male population in village B, C and E together

= >[90000*(2/5) + 120000*(3/5) + 150000*(13/25)]/3

= > [36000 + 72000 + 78000]/3

= > 62000

10) Answer: b)

The average male population of village B, C and E together

= >[90000*(2/5) + 120000*(3/5) + 150000*(13/25)]/3

= > [36000 + 72000 + 78000]/3

= > 62000

The average female population of village A, C and E together

= >[80000*(9/20) + 120000*(2/5) + 150000*(12/25)]/3

= > [36000 + 48000 + 72000]/3

= > 52000

Required difference = 62000 – 52000 = 10000
