- To finish a work, a sets aside half additional time than B.
Question 1:
To finish a work, a sets aside half additional time than B. In the event that together they take 18 days to finish the work, what amount of time might B take isn't that right?
A. 30 days
Feedback Suppose B takes x days. Then ,A takes 150x/100 days , i.e. 3x/2 days
=> 1/x+ 2/3x= 1/18
=> 5/3x= 1/18
=> 3x = 90
=> x= 30
Hence B takes 30 days.
=> 1/x+ 2/3x= 1/18
=> 5/3x= 1/18
=> 3x = 90
=> x= 30
Hence B takes 30 days.
B. 35 days
C. 40 days
D. 45 days
These questions are from this test. Would you like to take a practice test?
