Interestingly, got it when I was "sitting on the throne."
HOW many ways are there to place four marbles of different colours into four empty boxes? - See more at: http://www.straitstimes.com/news/sin....UzxY1SpY.dpuf
I thought the answer is 24. But it is wrong.
Tried the marble question again.
1. Put all 4 marbles in one box = put it in four different ways. Four combinations.
2. Put three marbles in one box and one in another box. 12 combinations right?
3. Put 2 marbles in one box and another two in another box. 3 combinations right?
4. Put 1 marble in one box and three marbles in another box. Same as (2).
So total = 19? But the answer given is 15. WHY?

Is an old one-hundred dollar bill worth more than a new one?
Ans: Yeah. $100 bill is always worth more than $1.
Can someone explain???
After Cheryl's birthday, now we have Cheryl's age. http://www.straitstimes.com/news/sin...s-age-20150515
Cheryl's age x (Albert's age)^2 = 144
For this, we can use Excel to generate the different combinations of ages.
So, we get:
1 x 12 x 12
4 x 6 x 6
9 x 4 x 4
16 x 3 x 3
36 x 2 x 2
144 x 1 x 1
Cheryl is unlikely to be age 1 and 144.
Cheryl's age + 2(Albert's age) = A certain bus number?
4 + 6 + 6 = 16
9 + 4 + 4 = 17
16 + 3 + 3 = 22
36 + 2 + 2 = 40
So, am I suppose to find out all the bus numbers in Singapore and choose the one which correspond to the combination? Ok, I try this method
http://www.sbstransit.com.sg/transpo...timetable.aspx
Bus 16 = yes
Bus 17 = yes
Bus 22 = yes
Bus 40 = yes
Am I now suppose to assume that the brothers cannot be so young (say 2,3 and 4 years old) and choose 6? Then Cheryl is only 4 years old. Hmm, ...

After going through a few solutions, I am able to understand these for:
1. Cheryl's birthday http://www.nytimes.com/2015/04/15/sc...hday.html?_r=0
2. Cheryl's age http://mustsharenews.com/cheryls-birthday-part-2/
Found the answer which I can understand: 1 x 4 (1 in each box) + 2 x 3 (2 in 2 boxes) + 4 (3 in 3 boxes) + 1 ( 4 in 4 boxes) = 15 ways https://www.facebook.com/TheStraitsT...52702108357115
Looks like all riddles solved by OTHERS.
1. In Singapore, you cannot take a photograph of someone with an umbrella. Why not?
2. Ah Loong lighted 50 candles to commemorate SG50. A wind blew and extinguished 15 of them. If no more candles were extinguished, how many candles does Ah Loong have left in the end?
