29. In the end, water in pail B is 4(5/12)+3(3/7)-1(1/4) more than original, water in pail C is 3(3/7) less than original.
So the result is 4(5/12)+3(3/7)-1(1/4)+3(3/7)=10(1/42)
31. In the end, Ahmad had 210 stickers, Khairul had 210 stickers.
before second round, Khairul had 210/(1-2/7)=294 stichers, Ahmad had 210-294*2/7=126 stickers.
At first Ahmad had 126/(1-1/3)=189 stickers, Khairul had 294-189/3=231 stickers
So the result is 4(5/12)+3(3/7)-1(1/4)+3(3/7)=10(1/42)
