Question

some notebooks were distributed equally among some students. if 10 students were less, each would get one notebook less . find the number of notebooks distributed​

Answer 1

Answer:

300

Step-by-step explanation:

Number of students-s

Number of notebooks each student get

n

Number of notebooks- sn

Now, let's build equations based on given:

1. 10 students less: (s-10) (n+1)=sn+s-10n-10-sn => s-10n+10

2. 15 student more: (+15) (n-1)=sn-s+15n-15-sn => s=15n-15

Comparing s in above equations we get value of n:

10n+10=15n-15

5n=25

n=5

s=10*5+10=60

Number of notebooks: 5*60=300

Answer 2

$•★Answer★•$

Let Number of students be s

Let number of notebooks each student get be n

Thus, number of notebooks - sn

$equation \: becomes \:$

1) 10 students get less : ( s-10 )

(n+1) = sn + s -10 n -10 - sn = s-10n +10

2) 15 students got more : ( s+15)

(n-1) = sn - s + 15n - 15 -sn = s = 15n - 15

$comparing \: s \: in \\ \: above \: two \: equations \\ \: we \: got \:$

10n +10 = 15n - 15

5n = 25

n= 5

s=10×5 + 10

= 60

Number of notebooks 5 ×60

= 300
