Step-by-step explanation:
hii mate hope my solution helps.....
let the ratio constant be 'x'
hence chocolates with a are 2x.....
chocolates with b are 4x....
second statement tells....a gives 4 chocolates hence (2x-4).....b receives 4 chocolates hence (4x+4).....new ratio is 5x and 9x
hence,
2x-4/4x+4 = 5x/9x
18x² - 36x = 20x² + 20x
-56x = 2x²
hence x is 28
initial chocolates are 56 and 112
