The table shows the percentage distribution of children in five villages (V1 to V5) and the percentage attending school. Total children = 5800; total attending school = 3600.
| Village | Children (%) | Attending School (%) |
|---|---|---|
| V1 | 16 | 15 |
| V2 | 24 | 28 |
| V3 | 11 | 14 |
| V4 | 18 | 21 |
| V5 | 31 | 22 |
What is the ratio of the total number of children from village V4 to the number of children attending school from the same village?
A22 : 21
B29 : 28
C29 : 21 ✓ Correct
D31 : 23
Correct answer: (C) 29 : 21
Explanation
The ratio is 29 to 21, so the answer is 29 : 21.
Children in V4 are 18% of 5800, which is 1044.
Children attending school from V4 are 21% of 3600, which is 756.
The ratio is 1044 to 756.
Dividing both by their common factor 36 gives 29 to 21.
So the total children to school-going children in V4 is 29 to 21.
Reducing the ratio to lowest terms is done by dividing both numbers by their highest common factor.
