Question

Shristi has a total rs780 currency notes in denomination of rs 10 , rs 20 , rs 50.
The ratio of rs 50 and rs 10 is in the ratio 3:2. If she has total 32 notes how many denomination of each note she have.

Answer 1

Answer:

let rs 50 notes =3x

let rs 10 notes=2x

then, 20 rs notes=32-(2x+3x)=32-5x

value of 50 rs notes=3x(50)=150x

value of rs 10 notes=2x(10)=20x

value of rs 20 notes=(32-5x)20=640-100x

according to the question

150x+20x+640-100x=780

70x+640=780

70x=780-640

70x=140

x=2

no of 50 rs notes=3x= 3×2=6

no of 10 rs notes=2x=2×2=4

no of 20 rs notes=32-5x=32-10=22
