Set S = {2, 3, 8, 11, x, y} $$Mean\ of\ S=\frac{2+3+8+11+x+y}{6}$$ $$7=\frac{24+x+y}{6}$$ Median = 5.5 and x<y From the mean of S $$24+x+y=42$$ $$x+y=18$$ From the median, an average of 2 numbers in the middle = 5.5 $$i.e\ \frac{a+b}{2}=5.5\ and\ a+b=11$$ From the numbers in the set 3+8=11.

Selling price = $80
Gross profit = 25% of the cost price
Profit = selling price - cost price
Let cost price = c
25% * c = 80 - c
0.25c = 80 - c
$$c=\frac{80}{1.25}=64$$
Gross profit = 25% * 64 = $16
