Answer:

Deveshi has a total of Rupees 590

Deveshi has a total of Rs 590 as currency notes in the denominations of Rs 50, Rs 20 and Rs 10. The ratio of the number of Rs 50 notes and Rs 20 notes is 3:5. If she has a total of 25 notes, how many notes of each denomination she has? 10 Rs note are 25-16=9.

Step-by-step explanation:

Let 50 Rs note be 3x

20 Rs note will be 5x

10 Rs note willbe(25-8x)

Total denomination=590

According to question

50(3x)+20(5x)+10(25-8x)=590

150x+100x-80x+250=590

170x=340

x=2

50 Rs note are 3x=3*2=6

20 Rs note are 5x=5*2=10

10 Rs note are 25-16=9.
