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:

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. |

42 * 23 = 966.
42 * 11 = 462.
42 * 11 = 462.

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.

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