The minimum value can be calculated using a short cut technique as given below.


Step 1 :Take the difference of all from 100( total number in question is 100)


100-100 = 0


100-80= 20


100-75= 25


100-70= 30


100-80= 20


95


Find the sum of all the differences = 95


Take the difference again from 100 = 100-95= 5
