Question

There are 4 qualifying examinations to enter into IIMs; CAT, BAT, SAT and PAT. an IITian can not go to IIMs through BAT or SAT. ACA on the other hand can go to theiims through the CAT, BAT and PAT but not through SAT. further there are 3 ways to became CA(viz.foundation, inter and final). find the ratio of number of ways in which an IITian can make it to IIM to the number of ways a CA can make it to the IIMs

Answer 1

Try drawing or counting the paths and lets compare drawings :)

Answer 2

I think this part
"further there are 3 ways to became CA(viz.foundation, inter and final"
is irrelevant to the question at the end

Answer 3

looks like three ways for CA and 2 ways for IIT but I feel silly now drawing considering it probably doesn't actually warrant a drawing...
