Question

a class teacher distributes some toffees among some students of his class .If there had been 4 students more each would have gotten 3 toffee less .But if there had been 4 students less each would have gotten 5 more toffees .find the total number of students​

Answer 1

orginal=x

total =y

if x+4=y-3

if x-4 =y+5

by adding both equations we get

2x=2y+2

therefore y=(2x-2)/2

= x-1

therfore total y= 3*5-1

14

therfo e there are 14 students in total
