A computers centre has four expert programmers . The centre needs four application programmes to be developed. The head of the computer centre , after stying carefully the programmes to be developed , estimates the computer time in minutes required by the respective experts to develop the application programmes as follows :

  Programmes
Programmes 1 2 3 4
  (Times in minutes)
A 120 100 80 90
B 80 90 110 70
C 110 140 120 100
D 90 90 80 90

How should the head of the computer centre assign the programmes to the programmers so that the total time required is minimum ?
