Study the following graph carefully and answer the question given below-
(a) In 1996, the population ,of village A as
well as B is increased by 10% from the year 1995 was 5000 and the percentage of
population below poverty line in 1996 remains same as in 1995, find
approximately the population of village B below poverty line in 1996.
(1) 4000
(2) 4500
(3) 2500
(4) 3000
(5) 3500
(b) If in 1997 the population of village D is
increased by 10% and the population of village G is reduced by 5% from 1995 and
the population of village G in 1995 was 9000, what is the total population of
village D and G in 1997?
(1) 19770
(2) 19200
(3) 18770
(4) 19870
(5) None of these
(c) If in 1995 the total population of the
seven villages together was 55000 approximately, what will be population of
village F in that year below poverty line?
(1) 3000
(2) 2500
(3) 4000
(4) 3500
(5) 4500
(d) If the population of village C below
poverty line in 1995 was 1520, what was the population of village F in 1995?
(1) 4000
(2) 6000
(3) 6500
(4) 4800
(5) none of
these
(e) The population of village C is 2000 in 1995, what will be the ratio of
population of village C below poverty line in that year?
(1) 207 : 76
(2) 76 : 207
(3) 152 : 207
(4) Data
inadequate
(5) none of
these
Solution –
(a) 5
Population of
village B in 1995= 5000 x(16 /13) ≈ 6150
Population of
village B in 1996= 6150 x(110 /100) ≈
6750
Population
below povert line = 52% of 6750 ≈3500
(b) 1
Population of
village D in 1995= 9000 x(17 /15) = 10200
Population of
village D in 1997= 10200 x (110 / 100)=11220
Population of
village G in 1997= 9000 x(95 /100) =8550
So total
population of villages D and G in 1997= 11220 + 8550= 19770
(c) 4
Population of
village F below poverty line= 55000 x (13 /100) x (149/100) ≈ 3500
(d) 3
Population of
village F in 1995= 1520 x (100 / 38) x (13 / 8) = 6500
(e) 2
