Question

A can do 1/6 of the work in 3 hours while B can do 1/4 of the work in 9 hour In how many days can both do it together?​

Answer 1

Step-by-step explanation:

where as 'A' can do 1/6 in 3hrs

where as 'B' can do 1/4 in 9hrs

= LCM of 6 and 4 is 12

so, convert it into like decimal

= 1×2/6×2= 2/12

= 1×3/4×3= 3/12

so,2/12=2

so,3/12=3

therefore 2×3 =6

it takes 6 days to complete the work by both 'A' and'B'

= 6
