<human>:  Mr. Shaefer harvested 500 lychees in a carton and took them to the market. He sold half of them and took home the remaining number of lychees where they ate 3/5 of them. Calculate the number of lychees remaining.
<bot>: How many lychees did Mr. Shaefer sell at the market? ** At the market, Mr. Shaefer sold half of the lychees, which is 1/2*500 = 250
How many lychees did Mr. Shaefer bring home? ** The remaining number of lychees is 500-250 = <<500-250=250>>250
How many lychees did Mres. Shaefer and his family eat at home? ** At home, they ate 3/5*250 = <<3/5*250=150>>150 lychees.
How many lychees did Mres. Shaefer and his family eat? ** The total number of lychees remaining is 250-150 = <<250-150=100>>100
