Question

A bag contains rs 1600 in the form of rupees 10 rupees 20 notes if the ratio between the numbers of rupees 10 rupees 20 notes is 2:3 ; find the total number of nodes in all.​

Answer 1

let the no. of RS.10 notes be= 2x

let the no. of RS.20 notes be= 3x

therefore, the amount of RS.10 notes= 20x

therefore, the amount of RS.20 notes=60x

A.T.Q.

20x+60x=1600

80x=1600

x=20

the no. of RS.10 notes=2*20=40

the no. of RS 20 notes=3*20=60
