How much does John's clean and jerk go up? ** His clean and jerk goes to 80*2=<<80*2=160>>160 kg
How much does John's snatch go up? ** His snatch increases by 50*.8=<<50*.8=40>>40 kg
How much does John's snatch go up? ** So his snatch is now 50+40=<<50+40=90>>90 kg
How much does John's total go up? ** So his total is 160+90=<<160+90=250>>250 kg
