Answer:

I don't know the answer

Answer 2

Answer:

Given Devshi has 590 Rupees

RS50, 20 & 10 are there ⇒ Total 25 notes

Rs50 & Rs20 ⇒3 : 5

Notes of Rs50 = 3x

Notes of Rs20 = 5x

Notes of Rs10 = 25−(3x+5x) = 25−8x.

Amount in 50 Rupee notes ⇒50×3x=150x

Amount in 20 Rupee notes ⇒20×5x=100x.

Amount in 10 Rupee notes ⇒10(25−8x)=250−80x

Total Amount =590

⇒150x+100x+250−80x=590

⇒250−80x=590−250

⇒170x=340

∴x=2

So Deveshi has

Notes of Rs.50=3(2)=6i

150(2) = 300Rs.

Notes of Rs.20=5(2)=10

100(2 )= 200Rs.

Notes of Rs.10=25−8(2)=9

10(9) = 90Rs
