Directions (1 - 4): The following figure represents flow of natural gas through pipeline between major cities A, B, C, D and E (in suitable unit). Assume that supply equals demand. Refer to it and answer the following questions.-
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.
3.
If the total demand in E is 80% of demand in A, what is the demand in A?
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.
4.
Assuming the information of question number 2 and 3 to be true, what is the total demand in the five cities?
