(C) Let Amit's speed be $A$ and Sujit's speed be $S$ key depressions per day.Given $S = 0.8A = \frac{4}{5}A$,so the ratio of their speeds is $S:A = 4:5$.Since they work together for $5$ days,the total work is $(S + A) 	imes 5 = 5,76,000$.Substituting $S = \frac{4}{5}A$,we get $(\frac{4}{5}A + A) 	imes 5 = 5,76,000$.$(\frac{9}{5}A) 	imes 5 = 5,76,000$,which simplifies to $9A = 5,76,000$.$A = \frac{5,76,000}{9} = 64,000$ key depressions per day.Since they work $8$ hours per day,Amit's speed in key depressions per hour is $\frac{64,000}{8} = 8,000$.

Amit and Sujit together can complete a data entry assignment in $5$ days. Sujit's speed is $80\%$ of Amit's speed and the total key depressions in the assignment are $5,76,000$. What is Amit's speed in key depressions per hour if they work for $8$ hours a day?
