Question

Looking around a farm, the number of chickens is four times the number of pigs. If there are a total of 48 legs between the chickens and the pigs, how many pigs are there on the farm?

Answer 1

27

Explanation:

4p+%2B+2c+=+78

4%2A12+%2B+2%2A15+=+78

48+%2B+30+=+78

78+=+78

Answer 2

There are 4 pigs on the farm

Explanation:

Let x be the number of pigs

We are given that the number of chickens is four times the number of pigs.

Number of chickens = 4x

No. of legs of 1 pig = 4

No. of legs of x pigs = 4x

No. of legs of chicken = 2

No. of legs of 4x chicken = 2(4x)=8x

There are a total of 48 legs between the chickens and the pigs

So,
`4x+8x=48`

`12x=48`

`x=(48)/(12)`

x=4

Hence There are 4 pigs on the farm
