The quantity moved from Avanti to Vidisha is
Explanation:
Demand at Panchal = 700
∴ Quantity of material flowing in the pipeline from Jyotishmati to Panchal = 700
Also, Flow from Vaishali to Jyotishmati + Flow from Vidisha to Jyotishmati = Demand at Jyotishmati + Demand at Panchal
∴ 300 + Flow from Vidisha to Jyotishmati = 400 + 700 = 1100
∴ Flow from Vidisha to Jyotishmati = 1100 − 300 = 800
Now, Flow from Avanti to Vaishali = Demand at Vaishali + Flow from Vaishali to Jyotishmati
∴ Flow from Avanti to Vaishali = 300 + 400 = 700
Also, Flow from Avanti to Vidisha = Demand at Vidisha + Flow from Vidisha to Jyotishmati
∴ Flow from Avanti to Vidisha = 200 + 800 = 1000
The diagram above shows the flow of the material in the pipelines and the demand at the respective points.
∴ Quantity of material moved from Avanti to Vidisha = 1000
Hence, option (d).
