In 2011, the total population of a village was 5280, Out of which 30% were female. In 2012, the total population increased by 10% in comparison to the previous year. If the number of females remained the same in 2012, what was the approximate percentage increase in the number of males in 2012 in comparison to 2011?

IXAMBEE SHORTCUT: we need not calculate the exact values . Let population in 2011 = 100, Male = 70 & female = 30 Now population in 2012 =100 +10 = 110, female = same = 30 So Male = 110 - 30 = 80 So % increase in population of males = (80-70)/70 X 100 =10/70 X 100 = 14.28% = 14% approx.
