Question

5) Working 4 hours a day, Samar can type 100 pages
of a book in 15 days. How many hours a day
should he work to finish the work in 12 days?​

Answer 1

Ashi takes 15 days to complete 100 Pages book with working 4 hours.

Therefore Ashi takes hours to complete the book in 15 Days i.e 15*4 =60 hour

so there is 1st equation 15*4 = 60

for second equation we have data that at 12days ashi have to complete 100 pages with Working X hours per day.

therefore 2nd eqation is

12*X = 60

therefore equating both equation we get

12*X = 60

X = 60/12

X = 5

Therefore after working on 5 hour Ashi will complete 100 Pages book in 12 Days.
