We know , W = R * T
Rate of Machine A = 15 golf clubs per hour
Time of Machine A = 6 hours
Here , W = 15 * 6 = 90 golf clubs
Work is equal for both the Machines, So
Time for Machine A = 1.5 hours
90 = Rate of Machine B * 1.5
Rate of Machine B = 90*10/15
60 (C)

Machine A fills production lot in 6 hours and machine B fills in 1.5 hours. So, machine B is 6/1.5 = 4 times faster than machine A.
So, machine B will produce 15*4 = 60 golf clubs per hour.
Option C is the answer.
So, machine B will produce 15*4 = 60 golf clubs per hour.
Option C is the answer.
