The parking charges of a car in Hyderabad Railway station for first two hours is 50 and 10 for each subsequent hour. Write down an equation and draw the graph. Find the following charges from the graph (i) For three hours (ii) For six hours (iii) How many hours did Rekha park her car if she paid 80 as parking charges?

The cost of notebook is twice the cost of a pen Write a linear equation in two variables to represent this statement (Take the cost of a notebook to be Rs x and that of a pen to be Rs y)

A lending library has fixed charge for the first three days and an additional charges for each day thereafter. John paid 27 for a book kept for seven days. If the fixed charges be x and subsequent per day charges be y, then write the linear equation representing the above information and draw the graph of the same. From the graph, find fixed charges for the first three if additional charges for each day thereafter is 4. Find additional charges for each day thereafter if the fixed charges for the first three days of 7.

Yamini and Fatima , two students of class IX of a school, together contributed Rs 100 towards the prime Minister's Relief Fund to help the earthquake victims . Write a linear equation which satisfies this this data. (You may take their contributions as Rs x and Rs y). Draw the graph of the same.

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body , express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also read from thte graph the work done when the distance travelled by the body is (1) 2 units (ii) 0 unit .

An auto charges 15 for first kilometer and 8 each for each subsequent kilometer. For a distance of ‘x’ km. an amount of ‘y’ is paid.
