| 5) | None of these | ||
Answer : 22000
Explanation :
Explanation :
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.

Direction : Study the following pie - chart and the table and answer the questions based on them. Proportion of Population of Seven Villages in 2013. ![]() Village % Population Below Poverty Line X 38 Y 52 Z 42 R 51 S 49 T 46 V 58 The ratio of population of village T below poverty line to that of village Z below poverty line in 2013 is: |

| 3) | 12:13 | 4) | 23:11 |
| 5) | None of these | ||
Answer : 23:11
Explanation :
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)Therefore, required ratio = 46% of (21% of N) / 42% of (11 % of N)= (46 x 21) /(42 x 11)= 23/11.
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.

Direction : Study the following pie - chart and the table and answer the questions based on them. Proportion of Population of Seven Villages in 2013. ![]() If the population of village R in 2013 is 32000, then what will be the population of village Y below poverty line in that year ? |
| 1) | 14500 | 2) | 15600 |
| 3) | 16200 | 4) | 17500 |
| 5) | None of these | ||
Answer : 15600
Explanation :
Explanation :
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.

| 1) | 1:2 | 2) | 2:1 |
| 3) | 2:3 | 4) | 3:4 |
| 5) | None of these | ||
Answer : 1:2
Explanation :
Explanation :
Total number of bikes of A type in year 2004, 2006, 2007 = 10,000 + 20,000 + 25,000 = 55,000
Total number of bikes of B type in year 2002, 2004, 2005 = 20,000 + 35,000 + 55,000= 1,10,000
So,ratio = 55,000 : 1,10,000 = 1:2
