Question

Hence, x = * 700
5. In the morning assembly of a school, 480 students are arranged in rows and columns. If there
are 4 more students in each row than the number of columns, find the number of students in
each row.
Let the number of students in each row be x.​

Answer 1

Answer:

24

Step-by-step explanation:

Solution:

Let the number of students in each row be x.

and the total numbers of row be y.

So,xy=480 ...(i)

and x=y+4 ...(ii)

Now,

(y+4).y=480

=> y²+4y-480=0

=> y²+24y-20y-480=0

=> y(y+24)-20(y+24)=0

=> (y+24) (y-20)=0

=> y=-24,20. Here,x=-24(neglated)

If y=20,x=20+4=24

So,number of students in each row =24.
