Question

students are 10 stand in rows if one student is extra in a row there would be 2 rows less if one student is less than in a row there would be three rows more find the number of students In a class​

Answer 1

let the number of students be x

number of students in each stand initially be y.

now,

10y=x( total student)...1

again if two students are increased in each stand

x=(10-2)(y+1).....2

x=8y+8=10y

2y =8

y=4

putting value in 1

x=10*4=40

total students in class is 40
