Raj and Ram working together do a piece of work in 10 days. Raj alone can do it in 12 days. Ram alone will do the work in?Options20 days50 days60 days40 days
Solution
To solve this problem, we need to find out how much work Raj and Ram can do in a day and then use that information to find out how long it would take Ram to do the work alone.
Step 1: Find out how much work Raj and Ram can do in a day together. Since they can complete the work in 10 days, they can do 1/10 of the work in a day.
Step 2: Find out how much work Raj can do in a day alone. Since he can complete the work in 12 days, he can do 1/12 of the work in a day.
Step 3: Subtract the amount of work Raj can do in a day from the amount of work they can do together to find out how much work Ram can do in a day. So, Ram can do 1/10 - 1/12 = 1/60 of the work in a day.
Step 4: Find out how long it would take Ram to do the work alone. Since he can do 1/60 of the work in a day, it would take him 60 days to complete the work alone.
So, the answer is 60 days.
