When Johny, Vincent and Fanny work together, it will take them 5 days to complete. When Johny, Vincent and James work together, it will take them 6 days to complete. And when Leo, James, and Fanny work together, it will only take them 4 days to complete the paiting job. How long will it take Johny, Leo, James, and Fanny to complete the job if they all worked together...?
2. Mr Harry brought home a bag of sweets for his grandchildren. He gave the first grandshild 2 sweets plus 1/13 of the remaining sweets. He then gave the second grandchild 4 sweets plus 1/13 of the reminder. To the third grandchild, Mr Harry gave 6 sweets plus 1/13 of the reminder. He continued the methode by giving the next grandchild extra sweets than the previous one and 1/13 of the reminder. The last of Mr Harry's grandchild took his share and found that there was no more reminder.Given that each of Mr Harry's grandchildren receives an equal number of sweets, how many grandchildren does Mr. Harry have. Also find the number of sweets each grandchildren receives...?
3. Three men are placed one behind another in front of a wall. The men are blindfolded and told that a hat will be placed on their head taken from a bin conmtaining 3 white and 2 black hats.
4. The blindfolder is then removed and each man is asked to determine the colour of the hat he is wearing. The third man who is furthest from the wall sees the other two men's hat and says, "I cannot tell what colur hat I am wearing." The second man who hears the third man's reply and sees the colour of the hat the first man is wearing says the same thing. The first man after hearing the replies of the other two men says, " I know the colour of the hat I am wearing." Do you know how he came to this conclusion and what is the colour is..?

It's just for funny....Hemmmm....Yummy...spent the time to joke with your friend....

Question This Week.....

There are two questions coming from my visitor :

1.

Tg ( p + q) = ½....(1)

Tg (p – q) = ¹/_3........(2)

Tg 2p = ...?

Answer

:

If : p + q = A  and p – q = B

With elimination we find :

2p = A + B

Tg 2p = Tg (A + B) =

=

2.

Sin (3x + 2y) = ¹/₈......(1)

Sin ((3x – 4y) = ¼ .....(2)

Sin 6y = ....?

Answer :

Misalkan

(3x + 2y) = A ® Sin A = ¹/₈

(3x – 4y) = B ® Sin B = ¼

With elimination we find :

6y = A - B

So sin 6y = sin (A – B)

Sin (A – B) = sin A cos B – cos A sin B

=

I hope my explanation make you clear and can understand.....
