let there be x no. of students...so money contributed by each student=Rs.10...so...total sum of money=Rs.10x...now according to the question... if there are 3 students more that each would have paid Rs.2 less...i.e. Rs.8...so total sum of money=(x+3)8...so 10x=(x+3)8...10x-8x=24...2x=24...x=12..so there were 12 students..
