Q:
A) 7 hrs | B) 6 hrs 10 min |
C) 5 hrs 25min | D) 8 hrs 15 min |
Answer: D) 8 hrs 15 min
Explanation:
Explanation:
A can write in 1hour = 32/6 pages
Similarly, B in 1 hour = 40/5 pages
Together (A+B) in 1 hour = 32/6 + 40/5 = 40/3
So, A+B write 40/3 pages in 1 hour
A+B write 110 pages in (3/40) x 110 Hours = 8 hours 15 min.
