Kavi , Babu and Sumita started a work. 10 days later Sumita left the work and Babu left the work after working for 6 days. In how many more days Kavi would have completed the rest of the work if Sumita take 40 days, Babu take 24 days and Kavi take 50 days to finish the work individually ?

Correct

Let the total work is LCM of 40, 24 and 50 = 600
Per day work of Kavi = 600/50 =12
Per day work of Babu = 600/24 = 25
Per day work of Sumita = 600/40 =15
Work done by sumita = 10 ×15 =150
Work done by Babu = 6 × 25 = 150
Work left for kavi = 600- (150+150 ) = 300
Time taken by kavi to do the left work = 300/12 =25 days

Incorrect

Let the total work is LCM of 40, 24 and 50 = 600
Per day work of Kavi = 600/50 =12
Per day work of Babu = 600/24 = 25
Per day work of Sumita = 600/40 =15
Work done by sumita = 10 ×15 =150
Work done by Babu = 6 × 25 = 150
Work left for kavi = 600- (150+150 ) = 300
Time taken by kavi to do the left work = 300/12 =25 days
