Assuming Z and Y are the two control variables, the following are the constraints laid out for maximizing the profit: Maximize profit (P) = 8X – 5Y Subject to Constraint-1: 2X + Y ≤ 1000 Constraint-2: 3X + 4Y ≤ 2400 Constraint-3: X + Y ≤ 800 Constraint-4: X – Y ≤ 350 Constraint-5: X ≥ 0 Constraint-6: Y ≥ 0 Which of the above constraints is a redundant one and does not have any effect on the solution?

Correct Answer Constraint-3

Calculation:

If the given constraints are drawn graphically then,

From the graph it can be seen that the constraint X + Y ≤ 800 does not becomes the part of the feasible region therefore it is a redundant constraint.

Read the following information carefully and answer the questions that follow: Seven persons Tina, Vini, Yasir, Rishi, Sanya, Pankaj and Urmila live on the separate floors of a 7- floor building. Ground floor is number one; second floor is number two and so on. Each of them goes to a city viz. Paris, Istanbul, Shanghai, Durban, London, Madrid and Dubai but not necessarily in the same order. Only three people live above the floor on which Sanya lives. Only one person lives between Sanya and the one who goes to Paris. Vini lives just below the person who goes to Madrid. Only three people live between the one who goes to Paris and London. The person who goes to Madrid lives on an even numbered floor. Urmila lives just above Rishi. Urmila does not go to London. Only two persons live between Pankaj and the one who goes to Durban. Pankaj lives above the person who goes to Durban. Yasir does not go to Istanbul.

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y. 
Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7.
