The information in the question let’s us solve for A using a ratio:
A / (A + 291) = 2 / 5
5A = 2A + 582
3A = 582
A = 194
Now we can use ratios again to solve for C:
11 / 2 = C / 194
2C = 2134
C = 1067
If I am interpreting your question (which you did not ask), you want to know how many bags were sold.
2430/10 = 243 bags with 10 apples in each bag were sold.
