Question

P can finish a work in 18 days. q can finish the same work in 15 days. i worked for 10 days and left the job. how many days does p alone need to finish the remaining work

Answer 1

your answer is 6 days.. take a look at picture.

Answer 2

Answer:

6

Step-by-step explanation:

Work done by P in 1 day = 1/18

Work done by Q in 1 day = 1/15

Work done by Q in 10 days = 10/15 = 2/3

Remaining work = 1 – 2/3 = 1/3

Number of days in which P can finish the remaining work = (1/3) / (1/18) = 6
