Let's assume that the total work is represented by W. Therefore, the work done by 8 men working for 10 hours in a day for 12 days can be written as:
W = 8 x 10 x 12 = 960
Now, let's assume that 4 men working for 16 hours a day take d days to complete the same work. Therefore, we can write:
4 x 16 x d = 960
Simplifying the above equation, we get:
d = 960 / 64 = 15
Therefore, it will take 4 men working for 16 hours a day 15 days to complete the same work.
Hence, the correct answer is option (A) 15.
W = 8 x 10 x 12 = 960
Now, let's assume that 4 men working for 16 hours a day take d days to complete the same work. Therefore, we can write:
4 x 16 x d = 960
Simplifying the above equation, we get:
d = 960 / 64 = 15
Therefore, it will take 4 men working for 16 hours a day 15 days to complete the same work.
Hence, the correct answer is option (A) 15.
