    Amit and Sujit together can complete an assignment of data entry in 5 days. Sujit’s speed is 80% of Amit’s speed and the total key depressions in the assignment are 576000. What is Amit’s speed in key depressions per hour if they work for 8 hours a day

  • 4800
  • 6400
  • 8000
  • 7200
  • None of these
  • Explanation:

    Ratio between work done by Amit and Sujit = 100:80 = 5:4

    Total work done by Amit = 576000×5/9

    = 320000

    Total working hours by Amit = 8×5 = 40 hour

    ∴ Amit's speed = 320000/40 = 8000
