Question

P can do a piece of work in 18 days. Q is more 20 % more efficient than P then how many days to complete work to Q​

Answer 1

Answer:

Step-by-step explanation:

Time taken by p:q = 25920:12960

                              =2:1

A takes 18 days and let B takes x days.

2:1 = 18:x

x = 36 days (B takes 36 days to finish the work)

Answer 2

Answer: 15days

Step-by-step explanation:

Q is 20% more efficient than P means, If Q's efficiency is 6 then P's efficiency will be 5.

Ratio of efficiency P : Q = 5 : 6

So, ratio of days P : Q = 6 : 5

Here, 6 unit is = 18 days

5 unit is = (18÷6)×5 days

= 15 days
