Answer : 218

275, 257, 301, 218, 265, 242, 201

Median is the middle of data set when arranged in ascending order

Lets arrange the numbers in ascending order

201 218 242 257 265 275 301

The median of these numbers is 257

Now we split the data set in to two halves using median 257

First half of data set is 201 218 242

The median of first half of data set is called the first quartile

218 is the first quartile.
