Question

Raju has a total of 30 currency note in his pocket of denomination 100 and 200 if the total is is rupees 5000 find the number of 200 rupees note​

Answer 1

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
