An interviwer is targeting a house where is attended to
by a woman: number of children? She saysThree . Would age? The product of the
ages is 36 and the sum is the same to the number of the House"13",answer. The
interviewer will be but a while back and tells the woman that the data you gave is not enough; the woman thinks and says: you are right, most studied piano.
This is sufficient for the interviewer to know the ages of the children. What
are?
ANSWER (Please click below)The interviwer asks ages and get as a response to the product of these is 36 and its sum the number of the House, look the number of this, which we do not know but yes. Pollster breaks down 36 at its factorial and performs the following combinations of ages. (all possible)
1-1-36
1-2-18
1-3-12
1-4-9
1-6-6
2-2-9
2-3-6
3-3-4
Only know which of these combinations of ages
add up the number of the House, then is given account that lacks some data, can
only be because there are two combinations that add up to equal:
1 + 6 + 6
= 13
2 + 2 + 9
= 13
He back
and knowing that bigest studied piano. It follows that there are only
increased, not two, so the ages should be 2, 2 and 9 years
