​The given line graph shows the number of deaths in a city from the year 2017 to 2022. Study the graph and answer the questions that follows.

What is the approximate percentage decrease in deaths from 2021 to 2022 and increase in deaths from 2020 to 2021 respectively?

Correct option is B

Given:

2021 to 2022 decrease in death 5000 to 3000

2020 to 2021 increase in death 3500 to 5000

Solution:

2021 to 2022 decrease death percentage = 5000- 3000 = 2000 

= $$\frac{2000}{5000}\times 10\% =40\%$$​​

2020 to 2021 increase death percentage = 3500 - 5000 = 1500

= $$\frac{1500}{3500}\times100\%= \frac{300\%}{7} = 42.85\%$$​  

Thus, Option(b) 40% and 42.85% is correct. ​
