How?
(b) What is Engineering economics? How it helps to the engineers in decision making? (3)
Q.2 (a) Define price elasticity. Explain the different methods to measure price elasticity (3)
of demand.
(b) LAD Enterprises sells mobile phones, currently charging £80 and earning £9,600 per (3)
week. It is considering a price cut of 20 per cent to increase its market share, estimating
its price elasticity of demand (PED) to be -1.6.
i. Estimate the effect of the price cut on LAD's revenue, stating any assumptions.
ii. If a competitor responds to the price cut by also reducing its price by 20 per cent,
estimate the effect on LAD's revenue, assuming the cross elasticity of demand
(CED) is 0.8.
iii. Compare the profits in (a) and (b) above with the original level of profit.
Q.3 (a) Define and give an example of each of the following demand terms and concepts. (3)
Illustrate diagrammatically a change in each.
i. Market demand curve
ii. Inferior good
iii. Complementary good
(b) Consider the following demand and supply equations for sugar: where P is the price (3)
of sugar per pound and Q is thousands of pounds of sugar:
QD = 1,000 - 1,000P
QS = 800 + 1,000P
a. What are the equilibrium price and quantity for sugar?
b. Suppose that the government wishes to subsidize sugar production by placing a floor
on sugar prices of $0.20 per pound. What would be the relationship between the quantity
supplied and quantity demand for sugar?

(b) The accompanying table shows the price and yearly quantity sold of souvenir
T-shirts in the town of North Zone according to the average income of the tourists
visiting.
ii. Using the midpoint method, calculate the income elasticity of demand when
the price of a T-shirt is Rs. 400 and the average tourist income increases
from Rs.250000 to Rs.40, 0000. Also calculate it when the price is Rs. 700
