Lakshmi is a cashier in a bank. she has currency notes of denominations 100,50 and 10 respectively. the ratio of the number of notes is 2: 3: 5. the total cash with lakshmi is 4. how many notes of each denomination does she have ?

the ratio of the notes is :   2 : 3 : 5  

let her have   2 * n number of rs 100 notes,   3 * n number of rs 50 notes,   and 5 * n   number of rs 10 notes respectively.

the total value of the currency notes :

2 n * rs 100 + 3 n * rs 50 + 5 n * rs 10   =   rs 4, 00, 000

=>     200 n + 150 n + 50 n = rs 4, 00, 000

=>     400 n = rs 4, 00, 000

  =>   n = 1, 000

hence,   there are 2n = 2,000 notes of rs 100   ,   3n = 3,000 notes of rs 50 and   finally ,   5 n = 5, 000 notes of rs 10..  

do i do it on a graph?
