Answer these based on the figure which represents the flow of natural gas through pipelines across major cities A, B, C, D and (in suitable units).Assume, that supply equals demand.
Total demand in E = Total input in E = $$550+800+650=2000$$
Now, E's demand is 80% of A,
=> Total demand in A = $$2000\times\frac{100}{80}=2500$$
=> Ans - (B)
