Proportion of Population of Seven Villages in 1997
The ratio of population of village T below poverty line to that of village Z below poverty line in 1997 is:
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.
