A 2-hp motor drives a sanding belt. If the efficiency of the motor is 87% and that of the sanding belt 75% due to slippage, what is the overall efficiency of the system?
The answer has to be 65.25%. Can someone please help me to work it out?

given
n1=87%= 0.87
n2=75%=0.75
solution
nt=n1 x n2 x 100
nt=0.87 x 0.75 x 100
nt= 65.25%
n1=87%= 0.87
n2=75%=0.75
solution
nt=n1 x n2 x 100
nt=0.87 x 0.75 x 100
nt= 65.25%
