HERE'S THE ANSWER .

______________________________

♠️ $\underline{ A\:and\:B\: complete\: work \:in\:4\:days}$

⏺️ $\bold{ A + B \:=\:1/4}$___ ( 1 )

♠️ $\underline{ A\:alone\: complete\: work \:in\:6\:days}$

⏺️ $\bold{ A \:=\:1/6}$ ___( 2 )

▶️ On ( 1 ) - ( 2 )

=> $\bold{ A + B - A\:=\:1/4 - 1/6}$

⏺️ L.C.M. = 12

=> $\bold{ B \:=\:( 3 - 2 )/12}$

=> $\boxed{ B \:=\:1/12}$

♠️ So B will alone complete work in 12 days

Answer 2

B = 3-2 / 12

B = 1 / 12

So B complete work in 12 days
