Answer:
180 houses
Explanation:
For every 10 flats, there are 30 bungalows. So, if there are 30 bungalows then there will be 100 flats in the village.
For every 5 flats there are in the village, there are 9 houses. There are 100 flats in the village. So, we can divide 100 by 5.
=20
20(9)=180
Therefore, there are 180 houses in the village.
