Q4. x and y are two positive real numbers, such that equation
2x + y ≤ 6; x + 2y ≤ 8
For which values of (x, y), the function f (x, y) = 3x + 6y will give maximum value
Answer : Option A
Explaination / Solution:
2x + y ≤ 6; x + 2y ≤ 8
x ≤ 1.33; y ≤ 3.33; ∴ option(B) and (C) is rejected becuase x >1.33
Option (D) is rejected x >10 / 3
