1. Taking all four countries together, what is the overall increase (%) in installed capacity of renewable energy in the year 2019, with reference to 2015?

1. 52.32%
2. 91.11 %
3. 117.32%
4. 121.81 %

Explanation: 86 – 45 x 100 = 91.11%

2. Between 2016 to 2017, which country registered maximum growth (%) in installed capacity of Renewable Energy?

1. X
2. Z
3. Y
4.T

Explanation: x= 15-13 / 13 = 15.38
y= 20-18 / 18 = 11.11
z= 12-10 / 10 = 20
t= 15-13 / 13 = 15.38

3. In any given year, compared to the previous year, which country(s) registered maximum growth (%)?

1. T
2. Z and Y
3. Y
4. X and Z

Explanation: X = 22-10 / 10 = 12/10 = 1.2
Y= 24-15 / 15= 0.6
Z= 20-8 / 8 = 1.5
T= 20-12 / 12 = 0.66

4. Which country registered maximum growth (%) by 2019 with reference to 2015?

1. Z
2.T
3. X
4. Y

Explanation: Z register maximum growth rate every year
By options Y is constant in between so can not be answer of maximum growth Hence X and Z is answer

5. For the country ‘Y’, what is the average annual growth (%) of renewable energy capacity?

1. ~10.85 %
2.~12.77 %
3.~13.25 %
4. ~11.65 %

Explanation: 2016 (18-15)/15 = 20
2017 (20-18)/18= 11.11
2018 (20-20)/20= 0
2019 (22-20)/20= 20
Total =51.11
Avg= 51.11/4= 12.775

1. 39
2. 91
3. 130
4. 169

Explanation: 39/30 x 100= 130

8. If 45 boys from the department ‘B’ did not donate blood, then the total number of students in the department ‘B’ is:

1. 120
2. 150
3. 80
4. 200

Explanation: 75 + 45 = 120
(120/60) x 100= 200

9. In case all the girls in the department ‘A’ donated blood, then the number of boys in the department ‘A’ who did not participate in the blood donation camp is:

1. 32
2. 48
3. 60
4. 56

Explanation: 40 x 100 = 160
25 160 x 40%= 64 girls donated blood
160- 64- 48= 48 not participated

10. What is the ratio of the number of blood donors in the department ‘A’ compared to the number of blood donors in ‘B’?

1. 1:5
2. 2:5
3. 9:16
4. 8:15
