Answer 1

HEY MATE HERE IS YOUR ANSWER

$\rule {168} {2}$

☑️ A and B can complete work in 4 days.

➡️ A + B = 1/4 - - - (1)


☑️ A alone complete work in 6 days.

➡️ A = 1/6 - - - (2)

Subtract 2 from 1

➡️ A + B - A= 1/4 - 1/6

L.C.M = 12

B = 3-2 / 12


B = 1/12

Therefore B will work in 12 days.
