Selection into (IIMs (Institutes of Management) is quite simple. In our coaching institute some students qualified CAT(The first stage of entrance into IIMs) but coincidentally the no. of boys who qualified the CAT was equal to the no. of girls. Besides these boys and girls got the calls from only IIM Ahmedabadand IIM Bangalore, but each of these from both the IIMs. 60% of the boys failed in the group discussion ( the second phase of the selection process) and thus equal no of boys (but distinct) appeared for the personal interview of IIM-A and IIM-B (interview is the third and final stage of selection of a candidate) but 20% of the boys who appeared for the interview of IIM-A and 60% of the boys who appeared for the interview of IIM-B failed. If it is possible that a candidate can receive the falls from more than one IIMs but he/she can face the interviewof only one IIM. Given that only 24 boys form our coaching institute were selected by the IIM and IIM-B also a candidate can appear for the next stage only if he/she qualifies the previous stage of the exam, then find the no, of girls who qualified the CAT (Common Admission Test).
