A can do a piece of work in 30 days. He worked for 6 days and B finished the remaining work in 48 days. B alone can do the whole work in how many days? Options: 1) 602) 55 3) 75 4) 70 ​

Answer»

Explanation:

Total time required by A to COMPLETE the work= 30 days

He WORKED for 6 days

Remaining work

24 days of work of A is completed by A and B both in 9 days

A×24 =(A+B)×9

A/9 = (A+B)/24

That means B/15 ( the values in denominators are their per day speeds with which they work)

So to total work = A×6 +(A+B)×9

=9×6 + 24*9

= 270 units

Time taken by B= 270/15 = 18 days
