Well let's work backwards to find out! Okay so subtract 11 from 200 (because you added 11) then you got 189 know and then you would divide the number by 3 (because you tripled it) so 189÷3=63 so let's try it with 63.
63 tripped is 189, 11 added to 189 is 200
So know know that it works we know it's our answer. 63
