We have two variable capacitors; each of them can be varied from 10pF to 500pF. What minimum and maximum capacitances can be obtained by combining them? (Answer is : 5pF and 1000pF) (Can I get the steps?)

putting two 500 in parallel maximum capacitance will be 500 +500=1000
putting two 10 in series minimum capacitance will be
1/c=1/10+1/10
c=5
putting two 10 in series minimum capacitance will be
1/c=1/10+1/10
