Question

The parking charges of a car at delhi railway station is rs. 50 for first 3 hrs and rs. 10 for subsequent hours. if for x hrs parking charge is rs. y. write a linear equation in two variable representing this information

Answer 1

Answer:

Given:

For 3 hours cost=₹50

1 hour cost =₹10

x hour cost =₹y

3hours:xhours

50₹:y₹

$3y = 50x$

$\frac{3}{50} = \frac{x}{y} ..........(1)$

Again apply unitary method,

1 hour:x hour

₹10. :₹y

$10x = y$

$\frac{x}{y} = \frac{1}{10} .........(2)$

from (1)

50x-3y=0

from (2)

10x-y=0
