From the test scores given:
<span> 42 45 50 57 60 63 66 70 73 78 85 87 90 94 95
splitting the values into 3 sets:
</span><span> (42 45 50 57 60 )(63 66 70 73 78)( 85 87 90 94 95)
from the first set we select the median:
</span>42 45 50 57 60
the median is 50

Mel had some cartons of milk. He sold 2/5 of the cartons in the morning. He then sold 3/4 of the remainder in the afternoon. 24
Yuki888 [10]
Sold 2/5 in the morning.....leaving 3/5
he sold 3/4 of 3/5 in the afternoon......3/4 * 3/5 = 9/20

2/5 = 8/20
9/20 - 8/20 = 1/20...so he sold 1/20 more in the afternoon.
so if 1/20 = 24, then 20/20 = 24*20 = 480

so he started with 480 cartons
