How much marks did you score in IIM Indore's IPMAT (to IPM STUDENTS)?

One of my friends graduated from IIM Indore and here’s what I got to know from him. 

• The students were only shown their composite scores in the exam from the 2015 IPMAT.
• The exact marks in the exam are not provided. 
• My friend had gotten a score of 64.3 with the highest reaching 85 and the cutoff for the interview being 42.
• The formula for the computation of the composite score is 60 (Candidate's Quant score – Minimum score) / (Maximum score - Minimum score) + 40 in Candidates Verbal Score – Min score/ Maximum score – Minimum score).
• From my friend’s guesses, she had attempted around 80 questions with an accuracy of around 85 to 90%. 
• So my friend’s marks in the exam must have been between 260-280 (following the +4, -1 marking scheme).

So you can assume that a score of 64 translates to around 270. But do keep in mind that the cut offs of the aptitude test changes every year.
