Pete had 3 boxes of marbles. He transferred 1/5 of the marbles from Box A to Box B. Then he transferred 1/4 of the marbles from Box B to Box C. Finally, he transferred 1/2 of the marbles from Box C to Box A. As a result, there were 134 marbles in Box A, 69 marbles in Box B and 50 marbles in Box C.
What was the total number of marbles in Box A and Box C at first?
