There were some blue marbles and white marbles in a bag. If 70 blue marbles were to be removed from the bag, the ratio of blue marbles to the white marbles would be 3:4.
If 112 white marbles were to be removed, the ratio of blue marbles to white marbles would be 8:7. When 48 more blue marbles were added into the bag, what % of all the marbles would be blue marbles at the end?

ANYBODY CAN HELP ME WITH THIS QUESTION?
USING MODEL METHOD!
NOT ALGEBRA!
