together, then the time taken to finish the same work is


​

Answer 1

Answer:

40/9 days (u can even reduce the answer if u want)

Step-by-step explanation:

Kiran finishes a book in 8 days.

Part of book completed in 1 day =1/8

Neha finishes a book in 10 days.

Part of book completed in 1 day=1/10

Part of book completed if they work together

=1/8+1/10

LCM is 40.

=5/40+4/40

=9/40

No of days required to complete the book if they work together =1/(9/40)days =40/9days

Hence it takes 40/9days to complete a book if both work togethere.

Hope it helps. :).
