1. B) Approximate
Average number of men from 2011 to 2015
= 65104+70391+70465+69395+71274/5 =
69326
2. C) total children in year range
20122014 = 25670+20314+21560 = 67544
Total women in the year range 2013
2015 = 63143+57630+65935 = 186708
Approximate % difference= (186708
−67544)/186708 ∗ 100 ≈ 64%
3. A) total children in 2016 = 21560/2 =
10780,
Total men in 2016 =
155498(10780+45000) = 99718
% increase in population of men in
2016 w.r.t 2011 = (99718−65104)/65104 ∗ 100 = 53.16%
4. E) average number of women = (60387+62516+63143+57630+65935+45000)/6
≈ 59102
It is given in 2016 men is double of
children so men = (155498−45000)/3 ∗ 2 ≈ 73665
Therefore average men in all year = (65104+70391+70465+69395+71274+73665)/6
= 70049
Difference in averages = 7004959102
= 10947
5. D) women and children in 2012 = 62516 +
25670 = 88186
Men and women in 2015 together =
71274+65935 = 137209
Required percentage = 88186/137209 ∗ 100 = 64.27%

15% = 12000

16% = 5120

18% = 5760

Flipkart

25% = 20000

24% = 7680

12320

6. A) Required %
= 20000−9600/9600 ∗ 100 ≈ 108%
7. E) required angle = (20−18)/100 ∗ 360 = 7.2°
8. C) number of HP laptops by highest seller is 12320
i.e. via Flipkart
Number of
Hp laptops by lowest seller is 6880 via Shopclues, so the ratio = 12320/6880= 77/43
9. D) after 10% increase total laptops sold by Snapdeal =
16000*110/100 = 17600,
Total
laptops sold by Flipkart = 20000,
%change = (20000−17600)/20000
∗ 100 =
12%,
Although
10% increase takes place next year in Snapdeal but it is 12% less than Flipkart
sales in current year.
10. A) Required ratio = [(8000+12320 +10560/3)]/[(5120
+3840 +5760)/3] = 30880/14720 = 193/92
