Question

If a school cafeteria needs c cans of soup each week for each student, and if there are s students in the school, for how many weeks will x cans of soup last?

A.  csx

B.  \frac{xs}{c}

C.  \frac{s}{cx}

D.  \frac{x}{cs}

E.  \frac{cx}{s}

Samridh09 · Accepted Answer

No. of soup cans per student per week = c
Hence total no. of soup cans per week = cs

No. of soup cans available = x
By dividing no. of soup cans by the requirement, we can find no. of weeks.
Therefore, the answer is x/cs, i.e. option D

Hey  Bunuel ,
The number indicating the total students is missing. Most probably it will be s students. Can you please check once?

Nikhil · Answer

Number of cans of soup each student needs for one week is 'c'
Number of students is 's'
Number of cans of soup required for one week is 'c*s'
Number of cans of soup required for 'w' weeks is 'w*c*s'

but we have 'x' cans of soup

=> x = wcs => w =  \frac{x}{cs}

Hence  option D

PKN · Answer

No of weeks x cans will last= Total no of cans available/No of cans needed per week for 's' students
 = \frac{x}{cs}  
Ans. (D)
