Answer Posted / thangavel
First i assume was how to get 600.
That is 60*10=600
given question is 10 bench is less than from available one.
then
60=available bench
10=student per seat
then i was sub 10 bench from available one so i got
50benches.Then i added 2 student per bench means
12 students per bench
so,finally
50*12=600{ (x-10)*12=600
x=50 then 50+10=60}
