PROBLEM OF THE WEEK #18









Ivanov, Jacobowski, Lebedev, and Malinkov are an architect, composer, dancer, and singer.

Ivanov and her husband invited the composer and his wife to dinner. The dancer said that he enjoyed playing chess with Lebedev. The singer complimented Malinkov on her excellent recipe for cabbage soup. What is the occupation of each person, and is that person male or female?

Since Ivanov and her husbend invited the composer neither of them can a be a composer.

Mrs. Cooper said...

Special recognition goes to Leslie, for being the first to comment!
Good job!(and you are right, neither can be the composer)
Okay, for the rest of you, who else can you rule out? Who cannot be the singer? Who cannot be the dancer?

Allen said...

Ivanov is not the composer and Lebedev is not the dancer
the singer is not Malinkov

Allen said...

ivanov is not the composer or dancer and malinkov isnt the singer

Allen said...

lebedev isnt the dancer

Allen said...

ivanov is the architect and is a girl

Allen said...

malinkov is the dancer and is a guy

Allen said...

malinkov is a girl actually

Allen said...

i cant decide on lebedev and jacobowski

gavriella said...

Ivanov is a female and the singer
lebedev is a male and the composer
Jocobowski is a male and a dancer
malinkov is a female architect
i did a chart

Danielle said...

Aw man! You guys are supposed to give hints not the answer...
I've been trying so hard to figure it out and now I don't have to. I started to make a chart then looked on the comments for help. Well, at least I tried...

Rebecca S. said...

I made a matrix and I found out that Ivamov and Malinkov are both girls and Jacobowinski and Lebedev are boys.

Iris said...

You have to draw one of those matrixes...

Allen said, ivanov is not the composer or dancer and malinkov isnt the singer-
How did you decide that? From which clue?

Yardi said...

Allen is right because first Ivanov is a girl and she cant be the composer because she invited the composer. Also, it says the singer complimented Malkinov on HER soup so it has to be a girl.

Iris said...

I found out that Ivanov is a female singer, and Malinkov is a female architect based on the matrix.

Lebedev and Malinkov are male, so Lebedev is the composer and Malinkov the dancer.

Yardi said...

Lebedev has to be the composer also in a matrix because he got invited with his wife to dinner and the dancer said he enjoyed playing chess with Lebedev. So he cant be the dancer and he's the only guy left so he is the composer and that means that Malinkov is the dancer

Yardi said...

wait scratch that Malinkkov is the architect because she got complimented on her soup

Yardi said...

OH I GOT IT!!! i wont say it on the blog though because your not supposed to say answers right?

Iris said...

nevermind, i already said that malinkov is the female architect. I mean that Jacobowski is the male singer

Iris said...

Oh yeah, and by the way, these last names are Russian. :)

Ethan said...

Malinkov and Ivanov are female while the other 2 are male

Ethan said...

I am pretty sure that i. is the singer and m. is the architect. l. is the composer and j. is the dancer.

Andrew Weatherly said...

this is a matrix type of problem

Jake B said...

I did a matrix too and i also agree with gavriella

Yacova said...

Ivanov is a girl the composer is a boy and Malinkov is a girl.
what is a matrix?

Ben S. said...

A matrix is a table that has the 2 or more values that correspond. For example, take names and jobs. (we are doing that)

I do not know if this will display correctly-
..............job._a__c_d__s_
Ivanov.........|__|__|__|__|
Jacobowski...|__|__|__|__|
Lebedev......|__|__|__|__|
Malinkov......|__|__|__|__|

Key
a= architect
c= composer
d= dancer
s= singer

That is a matrix. Using facts provided in the paragraph, infer who can or can't be in a certain job.
........................a_c_d_s_
Example: Ivanov |x|x|x|o|

Xs mean can't be that certain thing (like Ivanov can't be an architect)
and O's mean is (like Ivanov is the singer)

Also, cross out the column of singer when you circle. You can't have two singers.

P.S. I just made up the table. I have no idea if it is correct.
P.P.S. A matrix can be even bigger, with more names and jobs. Also, it can have other information such as hair color, etc.

Ben S. said...

P.P.P.S.
Sorry for the long post

P.P.P.P.S.
Sorry for the double post

Daniel Gordon said...

I= female, singer
J= male, dancer
L= male, composer
M= female, architect
(I made a chart to find my answer!)

R.J. said...

I Think That Ivanov is the singer.

Sloan Krakovsky said...

i made a matrix with the names on one side and the occupations on one side and when i found read if a person was a boy or a girl i wrote it next to their name so i think that Ivanov is a girl and she is the singer, Jacobowski is a boy and he is the dancer, Lebedev is a boy and he is the composer and Malinkov is a girl and she is the archatect.

Sloan Krakovsky said...

Btw everyone who said that you couldn't do it because the answer is already up... well try reading the question and figurng it out first before you read the coments thats what i do also the answers you read are not ALWAYS right so you can still do the the problem just to make sure.

Anonymous said...

i think daniel gordans right but i think knowing male and female really helped

Anonymous said...

what kinda names are lebedev and jacobowski

Mitch said...

Ivan-
Jacob-
be back later

Unknown said...

i is the singer j is the dancer l is the composer and m is the architect -i made a chart but i still dont know the gender because that is not on my chart yet

Unknown said...

this is noah i dont know why it is saying sammy but it is noah

noah said...

i think i fixed it

sean said...

i would make a matrix like ben and
put names on top going across and jobs going down then below the jobs going down i would have 4 sets of male and females and just do it like that.

noah said...

i just did a chart for their gender and I saw that i is a girl J is a boy L is a boy and M is a girl

noah said...

sean i dont get what you are saying

Sam said...

he's saying make a matrix like this

Key:a,c,d,s are the jobs. i,j,l,m are the names. Ma is male and Fe is female.

|a|c|d|s|Ma|Fe|
i|_|_|_|_|__|__|
j|_|_|_|_|__|__|
l|_|_|_|_|__|__|
m|_|_|_|_|__|__|
Ma|_|_|_|_|
Fe|_|_|_|_|

Sam said...

sorry it's a little messed up but that's the matrix i used to get the answer

Mrs. Cooper said...

Great commenting! I see that you picked up on the clue about male and female and that helps!

Ivanov is a female singer, Jacobowski is a male dancer, Lebvbedev is a male composer, and Malinkovis a female architect.
