Question 1
There are 48 blue and red marbles in four boxes A, B, C and D. In A there are equally many red and blue marbles. In B, C and D the red counts are respectively 2, 3 and 6 times the blue counts. The four blue counts are consecutive natural numbers, and the total blue count is 20 less than the total red count. Find the blue and red counts in each box, with reasoning.
