उत्तर
Assistants → A1, A2, A3, A4, A5
Clerks → C1, C2, C3, C4
Managers → M1, M2, M3
Executive officers → E1, E2
R = {(10,000, A1), (10,000, A2), (10,000, A3), (10,000, A4), (10,000, A5), (25,000, C1) (25,000, C2), (25,000, C3), (25,000, C4), (50,000, M1), (50,000, M2), (50,000, M3), (1,00,000, E1), (1,00,000, E2)}
