On a pig farm, pig #04892 ranks at the 84th percentile for weight. There are 245 pigs that weigh less on the ranch. How many pigs in total are being kept there?

Answer 1

Since pig #04892 ranks at the 84th percentile for weight, this means that there are 16% of pigs that weigh more than it.

If there are 245 pigs that weigh less than pig #04892, that means there are 16% of pigs that weigh more than it.

Let x be the total number of pigs on the farm.

So, we have:
0.16x = 245
x = 245 / 0.16
x = 1531.25

So, there are a total of 1531 pigs on the pig farm.
