Step-by-step explanation:
the population of a district was 7000000 in the year 2014. it increased at the rate of 7% per annum .what was its population in year 2012.
Let say population in Year 2012 was X
it increased by 7 % = (7/100) X = 0.07 X
Population in 2013 = Population in 2012 + increase
=> Population in 2013 = X + 0.07X = 1.07X
Now Again 7 % increase = (7/100) (1.07X) = 0.0749 X
Population in 2014 = Population in 2013 + increase
=> Population in 2014 = 1.07X + 0.0749X = 1.1449X
Population in 2014 = 7000000
1.1449X = 7000000
=> X = 7000000/1.1449
=> X = 6114071
Population in 2012 was 6114071
