Let A's 1 day's work = x and B's 1 day's work = y
Then, x + y = 1/30 and 16x + 44y = 1
Solving these two equations, we get x = 1/60 and y = 1/60
Hence, B alone shall finish the whole work in 60 days
Then, x + y = 1/30 and 16x + 44y = 1
Solving these two equations, we get x = 1/60 and y = 1/60
Hence, B alone shall finish the whole work in 60 days

Let's assume that A's work rate is "a units/day" and B's work rate is "b units/day".
Given information:
- A and B together can do a piece of work in 30 days.
- A having worked for 16 days, B finishes the remaining work alone in 44 days.
Work done by A in 16 days = 16 * a units
Work done by B in 44 days = 44 * b units
The total work done by A and B together is equal to the work done by A in 16 days plus the work done by B in 44 days.
Total work done by A and B = 16a + 44b
We also know that A and B together can do the work in 30 days.
So, the work done by A and B in 30 days = 30 * (a + b)
Since the total work done by A and B is equal to the work done by A and B together, we can equate the two equations.
16a + 44b = 30(a + b)
Simplifying the equation, we get:
16a + 44b = 30a + 30b
14a = 14b
a = b
This implies that A and B have the same work rate.
To find the work rate of B, we can substitute the value of a or b in any of the above equations. Let's substitute a = b:
16a + 44a = 30(a + a)
60a = 60a
a = a
We can see that the work rate of A and B is the same, which means they can do an equal amount of work in a day.
Since A and B together can finish the work in 30 days, and we know that A has already worked for 16 days, B will take the remaining days to finish the work alone.
Number of days B will take to finish the remaining work = 30 - 16 = 14 days
Therefore, B will take 14 days to finish the whole work alone.
Given information:
- A and B together can do a piece of work in 30 days.
- A having worked for 16 days, B finishes the remaining work alone in 44 days.
Work done by A in 16 days = 16 * a units
Work done by B in 44 days = 44 * b units
The total work done by A and B together is equal to the work done by A in 16 days plus the work done by B in 44 days.
Total work done by A and B = 16a + 44b
We also know that A and B together can do the work in 30 days.
So, the work done by A and B in 30 days = 30 * (a + b)
Since the total work done by A and B is equal to the work done by A and B together, we can equate the two equations.
16a + 44b = 30(a + b)
Simplifying the equation, we get:
16a + 44b = 30a + 30b
14a = 14b
a = b
This implies that A and B have the same work rate.
To find the work rate of B, we can substitute the value of a or b in any of the above equations. Let's substitute a = b:
16a + 44a = 30(a + a)
60a = 60a
a = a
We can see that the work rate of A and B is the same, which means they can do an equal amount of work in a day.
Since A and B together can finish the work in 30 days, and we know that A has already worked for 16 days, B will take the remaining days to finish the work alone.
Number of days B will take to finish the remaining work = 30 - 16 = 14 days
Therefore, B will take 14 days to finish the whole work alone.
