notes of each denomination does she have?

Answer 1

Answer:

Step-by-step explanation: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.

Then the total value of the currency notes will be:

    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..
