Amit takes 12 days less than the days taken by Bijoy to complete a certain work. If both, working together, takes 8 days to complete the work, find the number of days taken by Bijoy to complete the work, working alone.
Explanation
Let's assume Bijoy takes x days to complete the work. Then, Amit takes (x - 12) days. Their combined rate of work is 1/x + 1/(x-12) = 1/8. Solving this equation, we get x = 18. Therefore, Bijoy takes 18 days to complete the work.
