A rectangular room measures 7.5 meters in length and 3 meters in width. The room has a height of 3 meters. A spider sits 25 centimeters down from the ceiling at the middle of one of the short walls. A sleeping fly sits 25 centimeters up from the floor at the middle of the opposite wall. The spider wants to walk (i.e., move along the walls, floor, and ceiling only) to the fly to catch it. How can the spider reach the fly, walking just 10 meters? Is it even possible?

I have a box of one hour fuses. If I set one end of a fuse on fire, I know that the fuse will burn all the way to the other end in EXACTLY one hour. However, the fuses may burn unevenly [ie - it may take 59 minutes to burn the first half of a fuse, but only 1 minute to burn the other half]. Furthermore, all of the fuses may burn unevenly at a different rate. The only thing we know for sure is that each one takes 1 HOUR to burn completely. The Question: Given 2 of these fuses and a lighter, how can I time out 45 minutes precisely?

Two MIT math grads bump into each other while shopping. They haven't seen each other in over 20 years. First grad to the second: "How have you been?"
Second: "Great! I got married and I have three daughters now."
First: "Really? How old are they?"
Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there..."
First: "Right, ok... Oh wait... Hmm, I still don't know."
Second: "Oh sorry, the oldest one just started to play the piano."
First: "Wonderful! My oldest is the same age!"

given three daughters age multipication 72
so possible cases are
1 1 72 addition=74
1 2 36 addition=39
1 3 24 addition=28
1 4 18 addition=23
1 6 12 addition=19
1 8 9 addition=18
2 2 18 addition=22
2 3 12 addition=17
2 4 9 addition=15
2 6 6 addition=14
3 3 8 addition=14
3 4 6 addition=13
and the other man was unable to answer when compared to the building

so he must be confused
as a MIT grad can not be that weak in math

so there are two possible cases 338 and 266 where the sum is 14 ...........

again there can not be twins as hid old daughter bcoz he mentioned to have "the oldest one" in piano phrase so answer is 3 3 8

A+B, 1 hr. total pants=(12/4)+(12/3)=7
For 200 shirt A+B will require 200/(10/12)= 240/7 hrs.
For 200 pants A+B will require 200/7 hrs
Total time= (240/7)+(200/7)=440/7 or 62.85 hrs.

Plz try to solve the problem.....and explain the answer clearly.......

From a group of boys and girls , 15 girls leave.There then left 2 boys for each girl .After this 45 boys leave.There are then 5 girls for each boy.Find the no of girls in the beginning...??????

Reply Like? Yes | No

(10 years ago)

no. of girls is starting is 40

there is 2 equation
1.......b=2*(g-15)
2.......(g-15)=5*(b-45)

solving these two equations no of girls is 40 and no of boys is 50
you can check the answer with given condition...

Like? Yes (2) | No

(10 years ago)

let x boy y girls
2(y-15)=x.............1
//given 15 girls leaves 2 boys for a girl i.e;2 times the no of girls

After this that is now the girls are y-15 and boys are x 45 boys leaves
5(x-45)=(y-15)..............2
//given 45 boys leaves 5 girls for a boy i.e., 5 times the no of boys
solve these equations

solution: girls 40 boys 50
