2.
The ratio of population of village T below poverty line to that of village Z below poverty line in 1997 is:
Answer: Option
Explanation:
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)
 Required ratio = |
46% of (21% of N) | = | 46 x 21 | = 23/11. |

T = 21% ( in 21% of population 46% people are below powerty line).
Z= 11 % ( in 11% of T population, 42% people are below P line).
= 46% of 21/42% of 11.
= 46*21/42*11.
= 23/11.
Z= 11 % ( in 11% of T population, 42% people are below P line).
= 46% of 21/42% of 11.
= 46*21/42*11.
= 23/11.

@Praveen
The total population has to consider for calculating the ratios.. And so 46*21 / 42*11 would give u the answer 23:11

46*21/42*11.
Because 46/42 can be simplified into 23/21.
So, (23/21)*(21/11) = 23/11.
Because 46/42 can be simplified into 23/21.
So, (23/21)*(21/11) = 23/11.
