r/100 dollars per person per mile

one person going x miles will be charged rx/100
50% discount = rx/200

3such people = 3rx/200

rate*miles*passangers/discount

discount has to be in dollars so 1/2/100/1=200

rx3/200

A. 3xr / 2
B.3x / 200r
C. 3r / 200x
D.3xr / 200
E. xr / 600



Charge for One person and One mile = r cents
i.e. Charge for 3 persons and One mile = 3*r cents
i.e. Charge for 3 persons and 'x' miles = 3*r*x cents

After Discount, Charge = 50% of (3*r*x) cents
i.e. Charged Amount = (1/2)*(3*r*x) cents

But 1 Dollar = 100 Cents

i.e. Charged Amount in Dollar = (1/2)*(3*r*x)/100 Dollars
i.e. Charged Amount in Dollar = (3*r*x)/200 Dollars

Answer: Option

D
