Question

CBSE class 5
write a letter to your best ​

Answer 1

Answer:

Let the number of notes of Rs.10 be x

∴ The number of notes of Rs.20=50−x

According to the given condition,

⇒ 10x+20(50−x)=800

⇒ 10x+1000−20x=800

⇒ −10x=800−1000

⇒ −10x=−200

∴ x=200/10=20

∴ The number of notes of denomination of Rs.10=20

⇒ The number of notes of denomination of Rs.20=50−20=30
