- Answer is OPTION B
Circumfrence = 3.14 x 27 x 0.025 m = 21.20m
Total Distance travelled = 75 x 21.20 = 1590m
speed = 1590/60 = 26.85 m/s

- it is not dummy qus....when i visited capgemini in last month, i had same question like this but values are different. Can anyone ans plz!!!!!

- circumference=2*pi*r*=2*3.14*13.5=84.78(d=2r)
x=circumference*(no of rear teeth/no of front teeth)=84.78*0.26=22.82
total distance=75*x=75*22.82=1711
speed=1711/60=28.5(approx we can choose the answer) - 4 years agoHelpfull: Yes(0) No(0)
