I don't know whose challenge have they considered for changing the answers, but whosoever challenge was successful most of us gained something out of it.
Congrats for adding 6+ marks, that will surely propel your final gate score by more than 50 points.

The equation to use here is U= (ln(N2/N1))÷T2-T1. substitute N for the OD, T for time and U is specific growth rate. Since we are calculating N2/N1 you can directly substitute OD. You will have to calculate the dry cell weight or number of cells only if you need to compare 2 different microbes.

Thanks I got it it, quite simple question: 0.693/2=0.346.

To one of question I wrote 3.89 instead of 3.98 and range started from 3.90. I just lost 2 marks by 0.01 Sad final score "38.06"
