            Answer - 
            The feasible region determined by the system of constraints, 3x +5y ≤15, 5x +2y ≤10, x ≥0, and y ≥0, are given below

O (0, 0), A (2, 0), B (0, 3) and C (20 / 19, 45 / 19) are thecorner points of the feasible region. The values of Z at these corner pointsare given below
   |    Corner  point    |      Z = 5x +  3y    |    |  
   |    O (0, 0)    |      0    |    |  
   |    A (2, 0)    |      10    |    |  
   |    B (0, 3)    |      9    |    |  
   |    C (20 /  19, 45 / 19)    |      235 / 19    |      Maximum    |  
Hence, the maximum value of Z is 235 / 19 at the point (20 / 19,45 / 19)
