Question

Some notebook were distributed among some students if 10 student were less each would get 1 more notebook if 15 students were more each would get I notebook less Find the number of notebook disturbed

Answer 1

Step-by-step explanation:

if 10 student were less each would get 1 more notebook

• let's take students as x ,note book as y,

= (x-10)( y+1) -------(1)

if 15 students were more each would get I notebook less

= (x+15)(y-1) -------(2)

equate (1)&(2)

(x-10)( y+1) = (x+15)(y-1)

xy + x-10y-10 = xy-x +15y-15

xy + x-10y-10 - xy+x -15y+15= 0

2x-25y +5=0

2x -25y = -5

let's assume x= 10,y = 1

condition satisfied,

-5=-5

ANSWER : 1 NOTE BOOK / student
