Hi,

One possible solution is:

Let Vincent have 100u of money at first.
Let Ravi have (100u + $200) at first.

Hi everyone,

This is my first time posting here. Can anyone help to solve this?

Jim bought some chocolates and gave half of it to Ken. Ken bought some sweets and gave half of it to Jim. Jim ate 12 sweets and Ken ate 18 chocolates. The ratio of Jim’s sweets to chocolates became 1:7 and the ratio of Ken’s sweets to chocolates became 1:4. How many sweets did Ken buy?

Thank you.
