The ratio of Good oranges and Bad oranges = 5 : 4
Let's say the number of good oranges is 5x and the number of bad oranges is 4x.
Let the good oranges be eq 1 and bad oranges eq 2
Therefore since the number total number of bad oranges is 36, we can say that
4x = 36, right?
Solve for x in eq 2,
4x=36
divide both sides by 4:
x = 36 / 4
x = 9
Now that we know x, we can find the number of good oranges:
Put x=9 into eq 1;
5x = 5(9) = 45
So, the number of good oranges is 45.
To find the total number of oranges, add the good and bad oranges:
45 (good) + 36 (bad) = 81 (B)
There are 81 oranges altogether.
