Question

A can do 2/3 of a certain work in 16 days and B can do 1/4 of the same work in 3 days. in how many days can both finish work together?​

Answer 1

Answer:

Step-by-step explanation:

A can do 2/3 of a certain work in 16 days

Whole work will be done by A in 16 * (3/2) days = 24 days.

Therefore, A's 1 days work = 1/24

B can do 1/4 of the same work in 3 days

Whole work will be done by B in 3 * 4 days = 12 days

Therefore, B's 1 days work = 1/12

(A+B)'s one days work = 1/24 + 1/12 = 3/24 = 1/8

Therefore, A and B working together can finish the work in 8 days.
