Question

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 data. (You may take their contributions as Rs. x and Rs. y.) Draw the graph of the same.

Answer 1

Yamini and Fatima together contributed Rs. 100 towards the Prime Minister’s Relief Fund to help the earthquake victims. 

In that contribution of Yamini is R. x Contribution of Fatima is Rs. y 

Together Rs. 100. 

∴ x + y = 100 

∴ y = 100 – x.

x	20	40	50	60
y	80	60	50	40
