ya that's right .please help me also if u find any solution to this problem

will increases because force is equals to density*height*acceleration due to gravity , as density is equals to mass/volume therefore with the increase in weight the force acting increases

let no of student=x total money=y then from condition 1 total y rs is distributed to (x-8)students each having rs 10 10(x-8)=y.........(1) from condition 2 total x student get rs 5 each and they totally get (y-10)rs because 10 rs is undistributed. so 5(x)=y-10 5x+10=y..............(2) from eqn 1 & 2 after equating y we get 10(x-8)=5x+10 10x-80=5x+10 10x-5x=80+10 5x=90 x=90/5=18 on putting value of x in eqn 1 we get 10(18-8)=y 10*10=100 so total no of student=18 total money=100 got it????????????
