Question

Lakshmi is a cashier in a bank. She has currency notes of denominations? 100,
250 and 10, respectively. The ratio of the number of these notes is 2:3:5. The
total cash with Lakshmi is 4,00,000. How many notes of each denomination
does she have?
​

Answer 1

Answer:

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..

Answer 2

Step-by-step explanation:

Cash = 2 × 100 + 3 × 250 + 5 × 10 = 1000

1000 ------ 4,00,000

1 --------- 400

So,

100 Rs ------- 2 × 400 = 800

250 Rs ------ 3 × 400 = 1200

10 Rs --------- 5 × 400 = 2000
