Q:
A) 1/3 | B) 2/3 |
C) 1/6 | D) 5/6 |
Answer: C) 1/6
Explanation:
Explanation:
Given X can do in 10 days
=> 1 day work of X = 1/10
Y can do in 15 days
=> 1 day work of Y = 1/15
1day work of (X + Y) = 1/10 + 1/15 = 1/6
Given they are hired for 5 days
=> 5 days work of (X + Y) = 5 x 1/6 = 5/6
Therefore, Unfinished work = 1 - 5/6 = 1/6
