James decides to bulk up.  He weighs 120 kg and gains 20% of his body weight in muscle and 1 quarter that much in fat.  How much does he weigh now?
He gains 120*.2=<<120*.2=24>>24 kg in muscles
So he gains 24/4=<<24/4=6>>6 kg of fat
That means he gains a total of 24+6=<<24+6=30>>30 kg of bodyweight
So his new body weight is 120+30=<<120+30=150>>150 kg
#### 150
