Please answer the following question by reasoning step-by-step.
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?

150
He gains 120 *.

2 = 24 kg in muscles.

So he gains 24 / 4 = 6 kg of fat.

That means he gains a total of 24 + 6 = 30 kg of bodyweight.

So his new body weight is 120 + 30 = 150 kg.

.

So, the final answer is 150
