A group of men decided to do a job in 8 days. But since 10 men dropped out every day, the job got completed at the end of the 12th day. How many men were there at the beginning?
If x men were there on day one, there would be (x - 110) men on the 12th day.
Hence, on an average there were (x - 55) men.
The job takes 3/2 times the normal time.
Hence, the average number of people = 2/3
x - 55 = 2x/3
Hence, x = 165
The correct option is C.
