In a village, each of the 60% of families has a cow; each of the 30% of families has a buffalo and each of the 15% of families has both a cow and buffalo. In all there are 96 families in the village. How many families do not have a cow or a buffalo ?
-
- 20
- 24
- 26
- 28
Correct Option: B
Per cent of families having either a cow or a buffalo or both = 60 + 30 – 15 = 75
It means 25 per cent of families do not have a cow or a buffalo.
∴ Required number of families
| = 25% of 96 = 96 × | = 24 | 100 |
