A software company sets up m number of computer systems to finish an assignment in 17 days. If 4 computer systems crashed on the start of the second day, 4 more computer systems crashed on the start of the third day and so on, then it took 8 more days to finish the assignment. The value of m is equal to:

Options

  1. A150
  2. B180
  3. C160
  4. D125

Correct answer

A. 150

Step-by-step solution

aligned & 17 ~m = m +( m -4)+( m -4 2) + ( m -4 24) & 17 ~m =25 ~m -4(1+2 24) & 8 ~m = 4 24 25 2 =150 aligned
