✔ 最佳答案

1-1/10-1/12-9/20
=9/20-1/12
=27/60-5/60
=22/60
=11/30

Let x be the Mr.Tse's property originally
11/30X=3300000*4
11/30X=13200000
11x=396000000
x=36000000

Mr.Tse's property originally is36000000

給兒女的財產=$3,300,000 x 4
=$13,200,000

其餘給太太及一切基金的總數百份比=1/10 + 1/12 + 9/20
=6/60 + 5/60 + 27/60
=38/60
=19/30

給兒女的財產百份比=1 - 19/30
=11/30

那麼Mr.Tse的財產總值: (X) x 11/30=$13,200,000
(X)=$13,200,000 x 30/11
(X)=$36,000,000 [最後答案]

Mr.Tse's original property:
3300000X4/(9/20)/(1/12)/(1/10)
=13200000/(9/20)/(1/12)/(1/10)
=$3520000000
