Shaded region is represented by

  1. 2 x plus 5 y greater or equal than 80 comma   x plus y less or equal than 20 comma   x greater or equal than 0 comma   y less or equal than 0    
  2. 2 x plus 5 y greater or equal than 80 comma   x plus y greater or equal than 20 comma   x greater or equal than 0 comma   y greater or equal than 0    
  3. 2 x plus 5 y less or equal than 80 comma   x plus y less or equal than 20 comma   x greater or equal than 0 comma   y greater or equal than 0    
  4. 2 x plus 5 y less or equal than 80 comma   x plus y less or equal than 20 comma   x less or equal than 0 comma   y less or equal than 0    

The correct answer is: 2 x plus 5 y less or equal than 80 comma   x plus y less or equal than 20 comma   x greater or equal than 0 comma   y greater or equal than 0


    In given all equations, the origin is present in shaded area, answer (c) satisfy this condition.
