Hey I have a question,can anyone solve it.... A census taker approaches a house and asks the woman who answers the door,"How many children do you have, and what are their ages?" Woman: "I have three children, the product of their ages are 36, the sum of their ages are equal to the address of the house next door." The census taker walks next door, comes back and says, "I need more information." The woman replies, "I have to go, my oldest child is sleeping upstairs." Census taker: "Thank you, I now have everything I need." What are the ages of each of the three children?

The reason the Census taker could not figure out the children's ages for the first time was even having known the number on the house next door-- there were still 2 possibilities. The only way that the product could be 36 and still leave two possibilities is if the sum equals 13. These possibilities are 2+2+9 and 1+6+6. When the lady said that her "oldest" child is sleeping whe was giving a hint to the Census taker that there is an "oldest" child. Therefore, the ages of the children are 2,2, and 9.

There is a flaw in your question... especially there is a big time flaw in the address of the house next door... I am wondering, if kids come on holloween night and paint the second number besides the first number of the house.... Surreal... I agree with U_Day...

dear paras, your question has many possibilities, and it could be solved even without the number next door (which is always unknown to us). The answe can be found by the lowest common multiple theory or it could be simply done by breaking 36 down into integerial factors which are 1X2X2X3X3, it has several outcomes. 2,2 and 9 2,3 and 6 3,3 and 4 1,4 and 9 1,6 and 6 can be eliminated since she has the oldest child which could not be one between the twins. cheers

Explorer is absolutely right and there is no flaw in this question. With the several possible factors of 36 : 36*1*1 (sum=38) 18*2*1 (sum=21) 9*4*1 (sum=14) 9*2*2 (sum=13) 6*6*1 (sum=13) 6*3*2 (sum=11) 4*3*3 (sum=10) There is only one scenario when the census taker is not sure of the ages (i.e. when the sum=13). He obviously knows the address of the next house (even though we dont), and he would be able to tell for sure (even though we would not) if the sum was anything but 13. Since the lady had "an oldest child", he can tell that it is 9,2,2 instead of 6,6,1.

Still doesn't make sense that 9 2 2 is the only answer. eh. Couldn't it be anything Dsharma mentioned except 6 6 1? Mero goru ko barhai takka cha baa, 9 2 2 nai answer ho re, hehe.. aru hoina re. House number 13 nai ho re, aru hoina re, I'd say 6-3-2 lau jaa, that makes more sense to me Unless someone comes up with better explanation hehe... Math teacher haru le yestai garera lutcha, chahine nachahine question sodhera. :P 6*3*2 = 36 6 is "older" than 3 and 2 The house number next door is 11 :P

yah i agree kalanki bro, ma ni confused .. how are so sure the house next door is 13 or 11, it could have been 21??? wouldnt these be possible answers, like Dsharma said.. 36*1*1 (sum=38) 18*2*1 (sum=21) 9*4*1 (sum=14) 9*2*2 (sum=13) 6*3*2 (sum=11) 4*3*3 (sum=10) and by the way, we are one who is solving the problem not the census taker, so isnt it important for us to know the enough informaiton..

Sorry Bhinazu, You are off by 56.54%. It does not look as simple as the way you do it. Have to think little more. About the question you asked earlier, I thought that Conditions: If a girl is in the different side that of her BF, she will be kissed by the other boys even if they are with their GFs. meant that the guys cannot kiss the ladies if they are to go at the very same moment. Let me put you in more mathematical term: what I meant was at the instant when Bb get off the boat, a takes on the boat. So that the guy would not be able to kiss the lady. Anyway, if you really think that there is some other secured way, I can?t think on top of my head right now. Will post it later, if I come up with a better answer. No problem, confused.

Guys, Read the damn question carefully. IT SAYS THE PRODUCT WOULD BE 36. AND ALSO THE WOMEN SAID MY "OLDEST" CHILD IS SLEEPING UPSTAIRS. LONELYinTMIDWEST, your answer for 3,3,4 CANNOT add up to 13. THE ANSWER I GAVE IT TO YOU GUYS IS THE ONLY RIGHT ANSWER. There is no flaw in the question. :-)

Yes, The next door number must be 13 which has 2 solutions, otherwise there will not be confusion for him. 6,6,1 9,2,2 From the key word "Oldest Child" it becomes clear: 9,2,2 la aba aru tira kura agadi badhaaunu pardaa, mero prashna yas prakaar chha: Question: In Dashain Mangale bought 20 Khasis. He must cut the odd number of Khasis per day. He finished them within 7 days between Fulpati to Purnima. How was it possible?

Confused Bro, Yes U R Dumbed. 1.The census checked the next door. Agree? 2. 36*1*1 (sum=38) 18*2*1 (sum=21) 9*4*1 (sum=14) 9*2*2 (sum=13) 6*6*1 (sum=13) 6*3*2 (sum=11) 4*3*3 (sum=10) Agree? 3. If the sum(=address of next door) was 11 or 21 or 10 or 14 or 38, he doesn't have to be confused. But it must be 13 so that it made him confusion because the sum becomes 13 in 2 different caes as mentioned in 2. 4. Got it? Explorer is absolutely right.
