The population of a certain country increases at the rate of 30,000 people every month. The population of the country in 2012 was 360 million. In which year would the population of the country be 378 million?
(A) 2060
(B) 2061
(C) 2062
(D) 2063
(E) 2064
Population Increase Rate = 30,000 Per Month
Population in 2012 = 360 Million
Population in x year = 378 Million
378 Million - 360 Million = 18 Million
We want to calculate the year when the population increases by 18 Million
\(= \frac{18,000,000}{30,000} * \frac{1}{12}\) ====> 1/12 as we are converting per month to per year
\(= 50\)
YearsStart Year \(= 2012\)
We will add 50 Years \(= 2012 + 50 = 2062\)

Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent."
