time = ?

rate = t/m books/minutes
rate = 60t/m books/hr

time * rate * no. of machines = work

time * 60t/m * n = 10000

time = 10000m/60tn

Thus, D.

i have followed this
let n=1 , produces 10 books = t in 1 min(m)
So, 10 books =1 min
10,000 books = 1000mins ~ 16.6 hrs

putting n=1,m=1,t=10 in D and you will get 16.6hrs

10,000m/60tn
10,000*1 / 60*10 ~ 16.6hrs.
So, D
OA Pls

Another approach:

1machine

t books in m/60 hours

n machines

nt books m/60 hours

10000 books ????

m/60 / nt *10000

=10000m/60nt
