​

Answer 1

Answer:

(100,0)

Explanation:

x 0

50

100

y

100

50

0

Let the contribution of Yamini be x and that of Fatima be y.

According to problem,

x+

y=

100

...(1)

Now , putting the value

x=

0

in (1)

0+ y= 100

y= 100

So, the solution is (0,100)

Putting the value

x=

50

in (1)

50+ y= 100

y= 100–50

y= 50

So, the solution is (50,50)

Putting the value

x=

100

in (1)

100+ y= 100

y= 100–100

y= 0

So, the solution is (100,0)
