Lakshmi is a cashier in a bank. She has currency notes of denominations 100, 50 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?
Answers
Step-by-step explanation:
Let the ratio be x,
then , ratio be 2x : 3x : 5x.
so, 100×2x + 50×3x + 10× 5x = 400000
= 200x + 150x + 50x = 400000
= 400x = 400000
= x = 1000
hence, No. of 100 note = 2× 1000 = 2000
No. of 50 note = 3× 1000 = 3000
and , No. of 10 note = 5× 1000 = 5000.
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..
