Question

A and B can give a certain number of a basketballs in 12 days and 15 days respectively. they worked together for 5 days and then B leaves.In how many days will A finish the rest of the work?​

Answer 1

A will finish rest of the work in 11 days.

Step-by-step explanation:

Since we have given that

Number of days A can weave = 12 days

Number of days B can weave = 15 days

So, Number of units of work would be

L.C.M. of 12 and 15 = 60 units

Number of units done by A each day =

Number of units done by B each day =

If they work together for 5 days.

So, the number of units of A and B for 5 days would be

Remaining units = 60 - 45 = 55 units

Then, b leaves, so the remaining units would be done by A only.

so, Number of days A takes to finish the rest of the work would be

Hence, A will finish rest of the work in 11 days.
