Study the following pie-chart and the table and answer the questions based on them.
Proportion of Population of Seven Villages in 1997
11250
12760
13140
13780
Correct answer is B
Population of village Y in 1997 = 30000 (given).
Let the population of village V in 1997 be v.
Then, 15 : 10 = 30000 : v => v = (30000 x 10)/15 = 20000
Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.
Therefore Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
Study the following pie-chart and the table and answer the questions based on them.
Proportion of Population of Seven Villages in 1997
Find the population of village S if the population of village X below poverty line in 1997 is 12160.
18500
20500
22000
26000
Correct answer is C
Let the population of village X be x.
Then, 38% of x = 12160 => x = (12160 x 100)/38 = 32000
Now, if s be the population of village S, then
16 : 11 = 32000 : s => s = ( (11 x 3200)/16 ) = 22000
Study the following pie-chart and the table and answer the questions based on them.
Proportion of Population of Seven Villages in 1997
11 : 23
13 : 11
23 : 11
11 : 13
Correct answer is C
Let N be the total population of all the seven villages.
Then, population of village T below poverty line = 46% of (21% of N)
and Population of villages Z below the poverty line = 42% of (11% of N)
Therefore Required ratio = (46% of (21% of N))/(42% of (11 % of N)) = (46 x 21)/(42 x 11) = 23/11.
Study the following pie-chart and the table and answer the questions based on them.
Proportion of Population of Seven Villages in 1997
14100
15600
16500
17000
Correct answer is B
Population of village R = 32000 (given).
Let the population of village Y be y.
Then, 16 : 15 = 32000 : y => y = ( (15 x 32000)/16 ) = 30000
Therefore Population of village Y below poverty line = 52% of 30000 = 15600.
