The corner points of the bounded feasible region for an LPP are (0, 20), (3, 12), (6,8), (0, 15).
The objective function is \(Z=a x+\beta y\), where \(a, \beta>0\).
If the maximum of Z occurs at the corner points (3, 12) and (6,8), then the relationship between \(a\) and \(\beta\) is:
- A \(a=\frac{2}{3} \beta\)
- B \(\beta=\frac{4}{3} a\)
- C \(a+\beta=\frac{1}{2}\)
- D \(a=\frac{4}{3} \beta\)
Answer & Solution
Correct Answer
(D) \(a=\frac{4}{3} \beta\)
Step-by-step Solution
Detailed explanation
\(Z(3, 12) = Z(6, 8)\) \(a(3) + \beta(12) = a(6) + \beta(8)\) \(3a + 12\beta = 6a + 8\beta\) \(12\beta - 8\beta = 6a - 3a\) \(4\beta = 3a\) \(a = \frac{4}{3} \beta\)

Cancer detection is based on biopsy and histopathological studies. Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Do you know why mother's milk is considered very essential for the new-born infant? The yellowish fluid colostrum secreted by mother during the initial days of lactation has abundant antibodies (IgA) to protect the infant. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal. The exaggerated response of the immune system to certain antigens present in the environment is called allergy. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Drugs like barbiturates, amphetamines, benzodiazepines, and other similar drugs, that are normally used as medicines to help patients cope with mental illnesses like depression and insomnia, are often abused. Morphine is a very effective sedative and painkiller, and is very useful in patients who have undergone surgery.
