for ur understanding dont write it in ur notebook( u have to solve it by arrow method but by texting arrow cant be given so apply arrow as instructed- men upward means from 12 to 14..hours downward means4 to 8...days downward means 18 to X..)
Now,12/14=4/8×18/X
=12/14=36/4x
4X×12=36×14
X=36×14/48
=21/2
= 10 and half days
