If 11 students shifted to Edustar at the beginning of September, and the total students tutoring at Edustar has increased only by 7, then 4 students shifted out of Edustar at the beginning of September. Of these, atleast one should have shifted to Gurumath as its total number has increased to 39 from 38. the remaining 3 could have shifted to Matonline. So a minimum of no students needed to have shifted from Gurumath to Edustar
