A is 20% more èfficient than B. How much time will they working together take to complete a job which A alone could have done in 29 days

A = (120/100)B ---- (1) A*29 = (A+B)*N => N = 14.9

For an RC question that asks "which of the following would add least depth to the discussion mentioned in the topic", let us say there are 4 options with one of them being irrelevant to the discussion. In that case, do we pick the irrelevant option or do we pick the least important one among the other 3 options?

We would be choosing the irrelevant option if it is present otherwise if all the options are relevant to the discussion, we would choose the least important one.

Will work experience between 40 to 45 months consider bad for iims??

Not at all,It would be great advantage having that much experience which gives you 5 points and 10 points (out of 100) in some iims extra in selection process. Nearly 20% of people in iims are with experience around 3 years

The ideal amount of work experience is 24-36 months, in the sense that they get the most points during the selection process. work experience which is greater or lesser than that is still given some consideration but it is not as high as for those with 2-4 YoE.
