\(\large \color{black}{\begin{align} & \fbox{oldest}\rightarrow \fbox{thinnest} \rightarrow \fbox{Chutanmi} \rightarrow \fbox{youngest}=27 \hspace{.33em}\\~\\ & \fbox{youngest}\rightarrow \fbox{shortest} \rightarrow \fbox{Birianni} \rightarrow \fbox{tallest}=23 \hspace{.33em}\\~\\ & \fbox{youngest}\rightarrow \fbox{shortest} \rightarrow \fbox{thinnest} \rightarrow \fbox{Armani}=16 \hspace{.33em}\\~\\ \end{align}}\)

OpenStudy (mathmath333):

i first need to fins who is youngest tallest etc

OpenStudy (anonymous):

Does the book say what the answer is?

OpenStudy (mathmath333):

option b.) given in book

OpenStudy (anonymous):

tbh i really have no clue how to!

OpenStudy (mathmath333):

lol

OpenStudy (mathmath333):

@nubeer

OpenStudy (nubeer):

lol quite confusing

Parth (parthkohli):

we gotta make a table to first recognise who's what

Parth (parthkohli):

from the last piece of info, it seems that Armani is the guy who squares the numbers

OpenStudy (anonymous):

wow what a question

ganeshie8 (ganeshie8):

let f(x) = x/2, g(x) = x^2, h(x) = reverse(x)

Parth (parthkohli):

on the first piece of info, we can backtrack things pretty nicely. 27 ---> 72 ---> 144 ---> 12

OpenStudy (anonymous):

this is logic, it doesnt really involve any calculation @ganeshie8

OpenStudy (anonymous):

Chautanmi, or whatever, is the second born, thats for sure

OpenStudy (mathmath333):

biryani is the thinnest guy

Parth (parthkohli):

biryani lmao

OpenStudy (anonymous):

and if he is the second bor that means that Biranni is first born and Armani is last born

OpenStudy (astrophysics):

He can't be, he eats the most biryani

OpenStudy (anonymous):

*born

OpenStudy (mathmath333):

biryani also looks youngest

OpenStudy (mathmath333):

armani is shortest i think

OpenStudy (anonymous):

i think ther is a mistake in the question

OpenStudy (anonymous):

*there

OpenStudy (anonymous):

\[oldest \rightarrow thinnest \rightarrow Chutanmi \rightarrow youngest\]\[Second \rightarrow shortest \rightarrow Biranni \rightarrow tallest\]\[youngest \rightarrow shortest \rightarrow thinnest \rightarrow Armani\]

OpenStudy (mathmath333):

\(\large \color{black}{\begin{align} \begin{array}{|c|c|c|c|c|c|} \hline & tall & young & short & old & thin \\ \hline A & \times &\times &\checkmark &\times & \times \\ \hline B & \times &\checkmark &\times &\times & \checkmark \\ \hline C & \checkmark &\times &\checkmark &\times & \times \\ \hline \end{array} \end{align}}\)

OpenStudy (mathmath333):

is my table correct

OpenStudy (anonymous):

it isnt possible that none of them are oldest

OpenStudy (anonymous):

so no

OpenStudy (mathmath333):

\(\large \color{black}{\begin{align} \begin{array}{|c|c|c|c|c|c|} \hline & tall & young & short & old & thin \\ \hline A & \times &\times &\checkmark &\times & \times \\ \hline B & \times &\checkmark &\times &\times & \checkmark \\ \hline C & \checkmark &\times &\times &\checkmark & \times \\ \hline \end{array} \end{align}}\)
