12 Days of Christmas 🎅 GMAT Competition with Lots of Questions & Fun
A company uses pipelines to transfer fuel to different departments in the company. The flowchart above shows the movement of fuel from the main source A to different departments shown by the alphabets B to I. The fuel is transferred only once a day as per the combined requirement of the departments and the direction is shown by the arrow. The remaining fuel moves ahead only after meeting the requirement of a particular department. The maximum capacity of the pipeline is 700 liters.
For example, if 500 liters move from A to C, then 350 liters move from C to E after fulfilling the requirement at department C.
From each drop down menu, select the option that creates the most accurate statement based on the information given.
If the entire requirement of all departments is met, then liters of fuel flows in the pipeline EH, and liters of fuel flows out from the main source A.

Official Solution:
Drop-downs 1 and 2:
First, let's determine the total requirement of all departments. Summing up each department's requirements, we get a total of 1,400 liters. Since the maximum capacity of a single pipeline is 700 liters, meeting the requirements of all departments will require 700 liters flowing from A to C and another 700 liters flowing from A to B.
The combined requirement of departments C, E, and F is \(150 + 180 + 170 = 500\) liters. Therefore, out of the initial 700 liters flowing from A to C, \(700 - 500 = 200\) liters will remain to be transferred from E to H, compensating for the missing volume needed in the lower part of the flowchart.
Correct answer:
Dropdown 1: "200"
Dropdown 2: "1400"

A is splitting into two
The sum of A->C->E.... pipeline is 500
The sum of A->B.......->I is 900
But max capacity is 700
and so there is a EH pipeline so if 200 flows through EH then it will be 700 700 both at max capacity.
The total capacity is thus 1400.
200 and 1400 are final answers.
