Correct answer should be c). 80%
Applying V (mm/min) = N (No. of double strokes) * L (mm) * (1+m)
where 'm' is Quick return ratio.

Comparing with the equation : 1/(1+m) = 0.643
m=0.55;
OR time of return / time of cutting = 0.55
Speed of return /speed of cutting = 1.8

Hence 1.8:1
Option c) 80% is correct.
