You thought 10 ...then u doubled it... 10 X 2 = 20.... then you added 100..... 20+100=120... then you divided it by 2.... 120/2=60... then you subtracted the number you thought at first (10).... 60-10=50.... and that's the answer you are left with...

Let the no be x then (x*2+100)/2=x+50

Now x+50-x=50
