Question

Rahul can build a table in 6 days while Shyam can required 8 days for the same work. Working together, how many days would they require to make a table

Answer 1

6 8
48
8 6
work together they built in 48/14
24/7 is answer

Answer 2

Solution :

LCM ( 6, 8 ) = 24

so total work units = 24

Rahul's unit = 24/8 =3

Shyam's unit = 24/6 = 4

together units = 7

therefore time reqd = 24/7 days
