Question

A bag contains 1600/- in the form of 10/- and20/- notes. If the ratio between the numbers of 10/- and 20/- is 2:3 find the total number of notes in all.

Answer 1

Answer:

Number of 10/- note 40 & 20/- note 60

Step-by-step explanation:

let, 2x and 3x is the number of notes 10/- & 20/-

so the value of 10/- notes are 20x/- & the value of 20/- notes are 60x/-

so now

20x+60x=1600

or, 80x=1600

or, x=20

so number of 10/- notes are (20×2)=40

and number of 20/- notes are (20×3)=60
