At first situation, ratio = x/y = 1/5
5x = y -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5
Substitute the value of y from equation (1),
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5
Originally, There were 5 red marbles in the bag
Hope this helps!
Cos(180) = -1 if I’m not wrong, hope this helps
