What is number of units demanded in B?

A) 350 B) 400 C) 450 D) 500

View Answer Discuss

Answer & Solution

The input into B is 1200 units and the output from B is (250 + 550) = 800 units.
Hence,
Demand = 1200 - 800 = 400 Units.

Answer & Solution

C has a net output of 1100 units. If the demand is 225 at C, then to fulfill all conditions we need an input of 1325 into C. This will occur only if the value of M is 1075.

If the total demand in E is 80% of demand in A, what is the demand in A?

A) 2500 B) 2400 C) 4500 D) 5000

View Answer Discuss

Answer & Solution

The total demand in E = Total input into E.
  → 550 + 800 + 650 = 2000
$$\eqalign{ & = \frac{2000\times100}{80} \cr & =2500 \cr} $$
Hence, the demand in A will be 2500.
