Question

Answer

This is a question to test your understanding of ratio, pls take note that there were 3 types of color of marble, they are black , blue and red.

Number of black and blue marbles remain the same thru out the questions. 

If there are 4u blue marbles, there are 10u blue and black marbles. After adding some red balls

4u/ ( the new total) = 0.26

The new total =4u/0.26= 400u/26 = 200u/13 

So ratio of red marbles = (200u/13 – 10u)/(200u/13) = 70u/200u = 0.35

Note: Answer seemed too tedious, think there will be simpler solution.
