Question

27. 11. The car rental charges in a city comprise a fixed charge together with the charge for the distance covered. For a journey of 13 km, the charge paid is * 96 and for a journey of 18 km, the charge paid *131. What will a person have to pay for travelling a distance of 25 km ? [CBSE 2000]​

Answer 1

Answer:

Let fixed charge = Rs. x

and charge per kilometer = Rs. y

According to the question,

x + 13y = 96 …(i)

and x + 18y = 131 …(ii) i

On subtracting Eq. (i) from Eq. (ii), we get

x + 18y – x – 13y = 131 – 96

⇒ 5y = 35

⇒ y = 7

On putting the value of y = 7 in Eq. (i), we get

x + 13 (7) = 96

⇒ x + 91 = 96

⇒ x = 5

Hence, monthly fixed charges is Rs. 5 and charge per kilometer is Rs. 7

Now, amount to be paid for travelling 25 km

= Fixed charge + Rs 7 ×25

= 5 + 175

= Rs. 180

Hence, the amount paid by a person for travelling 25km is Rs. 180
