Question :
An organisation is experiencing a shortage of resources and has graphed a potential linear programing solution which shows its first product, televisions, on the horizontal axis and its other product, tablet, on vertical axis.
The iso contribution line is flat and downward sloping.Options :
A) The contribution per unit for tablets is higher than that for televisions
B) The contribution per unit for televisions is higher than that for tablets
C) the contribution for each product is similar
D) the contribution for one product is negativethe answer is A, can you explain why?
Is it because that the iso contribution line will touch the point on Y axis (tablets) first, when brought further from from origin?
Where did you find this question?
The reason I ask is that if you have copied it correctly then the question is nonsense.The iso-contribution line cannot be both flat and downward sloping.
Also, whichever contribution per unit is higher, the iso-contribution line will always be downward sloping! It will be at a steeper angle is televisions give a higher contribution that tablets, and a less steep angle if tablets give a higher contribution that televisions.
Have you watched my free lectures on linear programming.
This question is from kaplan exam kit. I checked the question, I have copied it correctly.
In that case there is a mistake in your exam kit because my previous reply is correct 🙂
(Have you check on the Kaplan website to see if there is an errata (correction) sheet for the exam kit?)
