Amit and Sujit together can complete an assignment of data entry in 5 days.
Sujit's speed is 80% of Amit's speed.
Total key depressions in the assignment are 5,76,000.
They work for 8 hours a day.
Formula used:
Let Amit's speed be A key depressions per hour.
Sujit's speed = 0.8A key depressions per hour.
Total work = (Amit's speed + Sujit's speed) × Total hours worked
Calculation:
Total hours worked in 5 days = 5 × 8 = 40 hours
Total speed = A + 0.8A = 1.8A key depressions per hour
Total work = 1.8A × 40 = 5,76,000 key depressions
⇒ 1.8A × 40 = 5,76,000
⇒ 72A = 5,76,000
⇒ A = 5,76,000 ÷ 72
⇒ A = 8,000
∴ Amit's speed is 8,000 key depressions per hour. The correct answer is option (3).
