उत्तर १
Let Madhu do 1 unit work in a day.
So Uma will do 2 units/day and Ramesh will do 3units/day.
So they will do 6 units in a day.
As they together take 6 days to complete the work so the total work = 6 x 6 = 36 units. Hence Madhu alone will do the work in 36 days.
So, option 36 days is the correct answer.
