Howdy!!


your answer is -
================

Given, A complete work in 12 days

and A and B together complete work in 8 days .

let, B complete work in x days .


therefore ,
$8 = \frac{12 x}{12 + x} \\ = > 96 + 8x = 12x \\ = > 4x = 96 \\ = > x = \frac{96}{4} = 24$

hence, B complete work in 24 days
