I believe the answer is the first one
A+b=-3, a=-3-b
ab=-35, and using a from above we get:
(-3-b)b=-35
-3b-b^2=-35
b^2+3b-35=0
b≈-7.6033 and 4.6033
So the two numbers are approximately -7.6033 and 4.6033
Let
x = number of rs 50
y = number of rs 20
z = number of rs 10
Because there are 25 total notes,
x + y + z = 25 (1)
The ratio of rs 50 to rs 20 is 3:5, therefore
x = 0.6y (2)
The total amount is rs 590, therefore
50x + 20y + 10z = 590
or
5x + 2y + z = 59 (3)
Subtract (1) from (3).
4x + y = 34 (4)
Substitute (2) into (4).
4*(0.6y) + y = 34
3.4y = 34
y = 10
From (2), obtain
x = 6
From (1), obtain
z = 25 - 6 - 10 = 9
