Answer: Let x students were in original group o each contributed150/x.now new group has x+5 student and each has contributed(150/x)-5. So now 150/(x+5)=(150/x)-5 or 150/(x+5)=(150–5x)/x or 150x=(150–5x)(x+5)or 150x=150x-5x^2+750–25xor 5x^2+25x-750=0or x^+5x-150=0 or (x+15)(x-10)=0 so x=10 or -15. As students number cannot be negative,hence there were 10 student in original group.
