The number of the blue cubes is 35 and the number of the red cubes is 20.
<h3>What is the ratio?</h3>The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.
Given that:-
- In a bag, there are red and blue cubes in the ratio of 4: 7
- I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7
The number of the blue cubes are calculated as:-
The two equations will be formed by the given data in the question.
7r = 4b
7r + 70 = 6b
Solving the above equation we will get the value of b.
4b + 70 = 6b
6b - 4b = 70
2b = 70
b = 35
7r = 4b
7r = 4 x 35
r = 20
Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.
