Amal can complete a job in 10 days and Bimal can complete it in 8 days. Amal, Bimal and Kamal together complete the job in 4 days and are paid a total amount of Rs 1000 as remuneration. If this amount is shared by them in proportion to their work, then Kamal's share, in rupees, is
The team completes the job in 4 days.
Since Amol needs 10 days to complete the job, in 4 days, he does 4/10th or 40% of the work.
Since Bimal needs 8 days to complete the job, in 4 days, he does 4/8th or 50% of the work.
Therefore, Kamal did 10% of the work and for doing 10% of the work, he gets 10% of the payment, i.e. Rs. 100.
The correct option is A.
