Question

Scooter charges consist of fixed charges and the remaining depending upon the distance travelled in km. if a person tavels 12 km,he pays rs.45 and for travelling 20km he pays rs.73 express the above statments in the form of simultaneous equations and hence find the fixed charges and the rate per km.

Answer 1

Answer:

3 rs and 3.50 rs

Step-by-step explanation:

Let the fixed charges be Rs x and the charges depending upon the distance travelled be Rs y

When the person travels 12 km and paid Rs 45

x +12y = 45...(1)

When the person travels 20 km and paid Rs 73

x +20y = 73...(2)

Subtracting (1) from (2), we get

8y = 28

y = 3.50

Using value of y in (1)

x +12(3.50) = 45

x = 45 – 42

x = 3

Thus, the fixed charges are Rs 3 and the charges depending upon the distance travelled be Rs 3.50.
