Correct option is A)

## In order to arrange the cartons of the same drink in the same stack, we have to find the greatest number that divides $144$ and $90$ exactly. Using Euclid's division algorithm, to find the H.C.F. of $144$ and $90$.

$144=90$ $×$ $1+54$

$90=54$ $×$ $1+36$

$54=36$ $×$ $1+18$

$36=18$ $×$ $2+0$

So, the H.C.F. of $144$ and $90$ is $18$.Number of cartons in each stack $=18.$

$144=90$ $×$ $1+54$

$90=54$ $×$ $1+36$

$54=36$ $×$ $1+18$

$36=18$ $×$ $2+0$
