The line chart given below shows the birth rate (per thousand persons) and death rate (per thousand persons) of countries P, Q, R and S in the year 2018. Which of the following statement(s) is/are correct? I. Birth rate of country Q is 9.2 percent more than country R. II. Birth rate of country R is 11.76 percent more than the birthrate of country S. III. Birth rate of country Q is 32 percent more than the birth rate of country S. Correct Answer Both I and II

Given:

Birth rate Q and R and S respectively = 8.3, 7.6 and 6.8

Concept:

The gain marks percentage = {(Gain marks)/(Total marks)} × 100

Calculation:

For statement l

⇒ The required % = {(8.3 - 7.6)/7.6} × 100 = (0.7/7.6) × 100 = (0.092) × 100 = 9.2

⇒ Hence, statement l is correct

For statement ll

⇒ The required % = {(7.6 - 6.8)/6.8} × 100 = (0.8/6.8) × 100 = (0.1176) × 100 = 11.76%

⇒ Hence, Statement ll is correct

For statement lll

⇒ The required percentage = {(8.3 - 6.8)/6.8} × 100 = (1.5/6.8) × 100 = (0.2205) × 100 = 22.05%

⇒ Hence, statement lll is wrong

∴ The required result will be "Both l and ll".
