He increased his back squat to 200+50=<<200+50=250>>250 kg

That means his front squat is 250*.8=<<250*.8=200>>200 kg

So he can do a triple with 200*.9=<<200*.9=180>>180 kg

So he moves 180*3 = <<180*3=540>>540 kg if he does three triples

John can front squat 80% as much as he back squats.  He used to back squat 200 kg but increased that by 50 kg.  He can do a triple equal to 90% of the amount he front squats.  How much weight will he move if he does three triples?
