Is the correct answer OPTION CHOICE 1 or the SEGMENT 1?
If its a linear equation problem, then the segment 3 makes sense. If its a parabola, quadratic equation, Segment 1 is the right choice.
See for Linear equation; y=mx+c.
Where y is % due, and x is time in months and c is the constant
at x=0, y=100 hence c=100. or y=mx+100 and at x=24, y=0 so m=-100/24.
The equation becomes y=100-(100/24)x.
For last segment 20-24 months, the balance should have been y (atx=20) - y( atx=24) = 16.67% but the balance was over and above 35%, hence it was behind time.
If you keep tracing back like this, the only segment that fits in section 3.
In order to trace if the project was behind or ahead of the regular pace, its better to start from the last month and check for WHAT SHOULD HAVE THE BEEN BALANCE? Question Stem didn’t ask for WHAT WAS THE FASTEST RATE.
Im also not getting this why if SEGMENT 1 is the correct answer choice. It is the right choice, only if the progression of the project was quadratic of the type y=ax2+bx+c
