Answer 2

Answer:

since total notes=25,

let ₹50 notes=3A

₹20 notes=5A

Then

₹10 notes=25- 3A- 5A = 25-8A,

Now according to the question, We get

50×3A +20×5A +10×(25-8A) =₹590,

150A +100A +250b-80A= ₹590,

170A =₹590- ₹250,

170A= 340,

Rhen

A= 340/170,

A=2

Therefore

₹50 notes=3×2=6

₹20 notes=5×2=10

₹10 notes=25-6-10= 9
