integrated reasoning

I think actual question has not been properly uploaded . here is the actual question :

can any one pls explain !! thanks a lot for help !!

question mentions min years of exp. to become a principal

for analyst it says<3 that means min =0
for associate it says 2 but can be relaxed(last point) so min again =0
for principal it says 4+ so min =4

sum all mins and we will have 4

4 yrs as analyst + 2 yrs of MBA
total 6
but it doesnt say full time MBA so I am not sure. what is the OA?

I would also go with 6 (min 4 yrs exp + 2 yr MBA)

what's the OA?

there was another similar question for the same information set provided about analyst, associate and partner:

John joined the bank as an Analyst when he was 22. One year later he asked for promotion to Associate. Is it possible that he will be promoted?

YES

[spoiler]I selected NO because 2 years is required from analyst to associate which could be relaxed if atleast 2 associates recommend the analyst strongly. No information is provided about any such reco or how much the 2 year restriction can be eased. I am really confused as to how much leeway do we have in such questions?[/spoiler]
