From Yahoo Sg:

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?"

Ans: 68.

Any kind souls to show me the steps to get the answer.

I tried but failed. thumbsdown.gif

Haiz... really worry for my son next time.
