    Please help the Census taker.

    A census taker came to a house where a man lived with
    three daughters. "What are your daughters' ages?" he asked.
    The man replied, "The product of their ages is 72, and the
    sum of their ages is my house number."
    "But that's not enough information," the census taker insisted.
    "All right," answered the farmer, "the oldest loves chocolate.

    Hi James,

    I am confused with the clue "the oldest loves chocolate". Because all the age group people loves chocolate. Using that clue how can i found that three daughter age? If you give that house number then i can try it..Otherwise i think i can't.

    Re: Please help the Census taker.

    Suresh the problem has sufficient information to solve.

    Let me give few hints,

    1. "But that's not enough information" the census taker insisted
    This is a key statement from census taker

    2. The former said "the oldest loves chocolate"
    IF you make use of the first hint then you will find that how useful ithis statement is?

    Hope this helps u

    May be the three daughters age is 3,3,8. If it is not then the answer is 2,6,6.

    Re: Please help the Census taker.

    Actually first i found all the combination of product 72 with three daughter. The combinations are...

    (1,2,36) and the sum is 39
    (1,3,24) and the sum is 28
    (1,4,18) and the sum is 23
    (1,6,12) and the sum is 19
    (1,8,9) and the sum is 18
    (2,3,12) and the sum is 17
    (2,4,9) and the sum is 15
    (2,6,6) and the sum is 14
    (3,3,8) and the sum is 14
    (3,4,6) and the sum is 13

    In that above table two combination values have the same sum. That is (2,6,6) and (3,3,8)

    Re: Please help the Census taker.

    "sorry i cant understand that why you choose the combination of three daughters be 2,6,6 or 3,3,8 ofcourse their sum is 14 in both the cases so how it could be the solution "

    The above question asked by sundarkms in private message....


    Here is the answer for his question...

    Sundarkms please look at the james hint...

    1. "But that's not enough information" the census taker insisted
    This is a key statement from census taker

    2. The former said "the oldest loves chocolate"
    IF you make use of the first hint then you will find that how useful ithis statement is?


    Why census taker told that is not enough information? Because he got the same sum for two or more houses. That's why i am taking those two set of values.

    I think now sundarkms clear....

    the oldest daughter's age is 6
    the second one's age is 4
    and the third one's age is 3

    6 * 4 * 3 = 72 and the sum of the same is 13 which is the house number.

    Hi,

    Hint is in it "the oldest loves chocolate."

    the ages are 8,3,3 for sure.

    Only oldest loves chocolate means a girl age 8 can eat chocolate. less chances for up-to age 3

    Re: Please help the Census taker.

    hi, in the information provided by the farmer, he hasn't mentioned that any of his daughters are twins, that gives a hint that the ages should differ from one another. hence, this was the possible solution to go for.
    6 + 4 + 3 = 13 and 6 * 4 * 3 = 72.

    Re: Please help the Census taker.

    We are talking about sum total to be 13 and the product of the total should be 72. if either of the constraint is not there.. then, there are n number of solutions.. and all the above mentioned solutions are correct..
