Question : The population of a city increases compounded by 10% annually. The present population of this city is 1,33,100. What was the population of the city 2 years ago?
Option 1: 1,01,000
Option 2: 1,10,000
Option 3: 1,21,000
Option 4: 1,00,000
Correct Answer: 1,10,000
Solution : $P=P{_0}×(1+r)^t$ where: $P$ is the present population, $P{_0}$ is the past population, $r$ is the annual growth rate (as a decimal), and $t$ is the number of years. Given, $P{_0} = 133,100$ $r = 10\%$ We have to find the population 2 years ago ($t=−2$
Question : The difference between the areas of two concentric circles is 264 cm2. What is the difference between the square of their radius? (use $\pi=\frac{22}{7}$)
Option 1: 70
Option 2: 140
Option 3: 84
Option 4: 64
Correct Answer: 84
Solution : Given: The difference between the areas of two concentric circles is 264 cm2. The area of the circle $=\pi R^2$ where $R$ is the radius. According to the question, $\pi R^2–\pi r^2=264$ ⇒ $\frac{22}{7}\times(R^2–r^2)=264$ ⇒ $(R^2–r^2)=\frac{264\times 7}{22}$ ⇒ $R^2–r^2=\frac{1848}{22}=84$ Hence, the correct answer
