The number of ₹20 notes are 4 times the number of ₹50 notes. The number of ₹50 notes are 3 times the number of ₹100 notes. There are total notes of denomination ₹20.

Answer 1

Answer:

60

Step-by-step explanation:

Let

No of Rs10 notes=x

then

No of Rs20 notes=x/5

No of Rs50 notes=x/20

No of Rs100 notes=x/60

now

10x+20(x/5)+50(x/20)+100(x/60)=5450

10x+4x+(5/2)x+(5/3)x=5450

(109/6)x=5450

x=5450×6/109

x=300

No of Rs20 notes=60
