|1) 20 men take 10 days to complete a job working 12 hours a day. Find the number of men required to complete a job, twice as large, in 30 days working 8 hours a day|
|A) 15||B) 30|
|C) 25||D) 20|
|View Answer|| RRB Se Exam 2014 yellow colour|
In my perception, answer for the above question is 20.
Description: 20 men -- 10days -- 12hrs means total hours required = 2400hrs
similarly next task is twice as the large so time required is = 4800hrs
so men * 30 * 8 = 4800hrs
Hence men required = 20.
Kindly let me know whether i am right or wrong.
Thanks in advance.
