Answer 1

Answer:

X+Y+=100

Step-by-step explanation:

here x=P

and, Y=Q

total amount=100

total students= P and Q

so X+Y=100

Answer 2

Step-by-step explanation:

Answer

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)
