Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Also, as a general rule, whenever a trend line is shown in the form of e^(rt) or Ae^(rt), where t is the time period, the value of r gives us the growth rate. You can confirm this by putting t=2,3,4... and then finding the annual growth rate by finding percentage change in Y from one period to the next.

Firstly, the question is incorrectly written. Trend growth rate is always in the form of e^(rt); t or the time period is part of the power term. So the question actually is = Y = 136e^(0.021T) Coming to the answer, the growth rate is 0.021 or 2.1%. Just put the value of T as 0 and then as 1. This will give the value of Y in current and next time period. Then calculating the percentage change in Y will give 0.021 or 2.1%. If this explanation is not very clear, let me know. I'll show the calculation on a paper.
