The following pie-chart shows proportion of population of seven villages in 2009. Study the pie-chart and answer the questions that follow:
In 2010, the population of 'Y" and 'V' increases by 10% each and the percentage of population below poverty line remains unchanged for all the villages. If in 2009, the population of village Y was 30000, then the below poverty line population of village 'V' in 2010 is ...............
11250
12760
13140
13780
B.
12760
Population of Y in 2009 = 30000
15% = 30000
∴ Total population of all villages
Total population of village 'V' in 2009:
Population of village V in 2010:
∴ Population of village V below poverty line in 2010:
