Rate Machine A = 1000/5 = 200 Widgets /h
Rate Machine B = 1000/10= 100 Widgets/h
Let Rate of Machine C = X
Rate of 3 Machines Working sim together independently = x + 100+200
x+100+200= 1000/3
so x = 1000/3- 300 = 100/3 wid /h
So machine c can produce 100 Widgets in 3 hrs
so 1000 Widgets in Total 30 Hours
So answer is E )
Rate Machine B = 1000/10= 100 Widgets/h
Let Rate of Machine C = X
Rate of 3 Machines Working sim together independently = x + 100+200
x+100+200= 1000/3
so x = 1000/3- 300 = 100/3 wid /h
So machine c can produce 100 Widgets in 3 hrs
so 1000 Widgets in Total 30 Hours
So answer is E )

Rate of A = 1000/5 = 200 units/hr
Rate of B = 1000/10 = 100 units/hr
Rate of A+B+C = 1000/3 = 333 1/3
Thus, Rate of only C = 333 1/3 - 300 = 33 1/3 = 100/3
Thus to produce 1000 units, C will take =1000/(100/3) = 30 hours
Options E
Rate of B = 1000/10 = 100 units/hr
Rate of A+B+C = 1000/3 = 333 1/3
Thus, Rate of only C = 333 1/3 - 300 = 33 1/3 = 100/3
Thus to produce 1000 units, C will take =1000/(100/3) = 30 hours
Options E
