Question

The charges for renting and SUV vary with the distance travelled by it, apart from a fixed cost of Rs.1000. Charges start from Rs.15/km and reduced by Rs.1 for every 10km travelled. If a customer was charged Rs.1606 for renting an SUV, what was the distance travelled by him (in km)?

Options:
A. 38km
B. 36km
C. 46km
D. 30km​

Answer 1

Answer:

et the total charge = y

the fixed charge = c

charge per km = x

So if a person travels z km, the charge: y = c + zx

for 12km, charge = 89

89 = c + 12x  ---------------(1)

for 20 km, charge = 145

145 = c + 20x  -------------(2)

solving equation 1 and 2, we get,

c = Rs. 5

x = Rs. 7/km

So the charge is: y = Rs(5 + 7x)

For 30km, charge, y = Rs.(5+7×30) = 5 + 210 = Rs. 215
