Question

Two students A and B together contributed Rs. 100 towards the Prime Minister's Relief Fund to help the earthquake victims, Write a linear equation to satisfy the above data and draw its graph.

Answer 1

Let A contibutes X rupees and B contributes Y rupees.

Then according to question,

X + Y =100 ...........1

Put value of X = 0 in equation 1, we get

y = 100

Put value of X = 50 in equation 1, we get

50 + Y = 100

=> Y = 100 - 50

=> y = 50

Put value of X = 100 in equation 1, we get

100 + Y = 100

=> Y = 100 - 100

=> y = 0

So different solution of eqaution 1 is:

X : 0 50 100

Y: 100 50 0
