###Human: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine.  The second drink is 3 times more caffeinated per ounce but only 2 ounces.  He then takes a caffeine pill that has as much caffeine as his 2 drinks combined.  How much caffeine did he consume?, ### Assistant: The second drink was 2/12=1/6 the size of the first drink
So it had 1/6*3=1/2 the caffeine
That means it had 1/2*250=125 grams of caffeine
So the total amount of caffeine he drank was 125+250=375 grams
So he consumed 375*2=750 grams of caffeine for the day 
 So the answer is :  750
