A and B individually can complete the work in 20 days
and 30 days respectively. If the time taken by C alone to complete the work is 1.25 times the time taken by A and B together to complete the work, find the time taken by C to complete the work while working alone.Solution
Time taken by A and B together to complete the work = (20 × 30)/ (20 + 30) = 12 days Time taken by C alone to complete the work = 1.25 × 12 = 15 days
