Question 1

If A can complete a work in 5 days, and B in 11 days, how long will they take together?
Time = (A * B) / (A + B) = (5*11)/(5+11) = 3.44 days.

Question 2

If A can complete a work in 2 days, and B in 8 days, how long will they take together?
Time = (A * B) / (A + B) = (2*8)/(2+8) = 1.6 days.

Question 3

If A can complete a work in 4 days, and B in 8 days, how long will they take together?
Time = (A * B) / (A + B) = (4*8)/(4+8) = 2.67 days.

Question 4

If A can complete a work in 4 days, and B in 8 days, how long will they take together?
Time = (A * B) / (A + B) = (4*8)/(4+8) = 2.67 days.

Question 5

If A can complete a work in 3 days, and B in 9 days, how long will they take together?
Time = (A * B) / (A + B) = (3*9)/(3+9) = 2.25 days.

Question 6

If A can complete a work in 2 days, and B in 9 days, how long will they take together?
Time = (A * B) / (A + B) = (2*9)/(2+9) = 1.64 days.

Question 7

If A can complete a work in 5 days, and B in 12 days, how long will they take together?
Time = (A * B) / (A + B) = (5*12)/(5+12) = 3.53 days.

Question 8

If A can complete a work in 2 days, and B in 6 days, how long will they take together?
