Answers
Given : X is four times as efficient as Y in respect of doing a particular work. Working together they complete the work in 16 days
To Find : In how many days y working alone will be able to half the work?
Solution:
Let say Y 1 day work = a
X is four times as efficient as Y
=> Y 1 day work = 4a
Working together they complete the work in 16 days
=> Total Work = 16a + 16(4a)
= 16a + 64a
= 80a
half the work = 80a/2 = 40a
Y 1 day work = a
=> y working alone will be able to half the work = 40a/a = 40
in 40 Days y working alone will be able to half the work
