Question

In an envelope there are some 5 rupee notes and some 10 rupee notes. Total amount of these notes

together is 350 rupees. Number of 5 rupee notes are more by 10 than number of 10 rupee notes. Then

find the number of 5 rupee and 10 rupee notes.​

Answer 1

Answer:

let the number of 10 rupee notes are x

so the number of 5 rupee notes are x+10

so,

10x+5(x+10)=350

10x+5x+50=350

15x=350-50=300

x=300/15=20

so,the number of 10 rupee notes are 20 and number of 5 rupee notes are 20+10=30
