A vendor has six jugs of punch with capacities of 13, 15, 16, 21, 21, and 22 gallons. One jug, which he keeps for himself, is full of blue punch. The other five jugs are full of red punch. Without opening any of the jugs, he sells 1/3 of the red punch to Randy and the remaining 2/3 of the red punch to Lisa. How many gallons of the blue punch did he keep for himself?

The vendor  sells the jugs containing  13 , 15, 16, 21 and 22 gallons

This totals  87  gallons

1/3  of this =  29 gallons  which means that he sells the jugs containing 13 and 16 gallons to Randy

The remaining 2/3 = 58 gallons which means that he sells the jugs containing 15, 21 and 22 gallons to Lisa 

 

He  keeps the  remaining  jug which contains 21 gallons of  blue punch
