Answer 1

Question:

Lakshmi is a cashier in a bank. She has currency notes of denominations  ₹100, ₹50 and ₹10. The ratio of the number of these notes is 2:3:5 respectively. The total cash with Lakshmi is ₹4,00,000. How many  notes of each denomination does she have?​

Solution:

Let the number of ₹100 notes be $2x$

Let the number of ₹50 notes be $3x$

Let the number of ₹10 notes be $5x$

To find the number of notes Lakshmi has, we need to multiply the money with its respective ratio

$2x\times100=200x$

$3x\times50=150x$

$5x\times10=50x$

Total cash Lakshmi has = ₹4,00,000

$200x+150x+50x=4,00,000$

$400x=4,00,000$

$x=\frac{4,00,000}{400}$

$x=1,000$

So, Lakshmi has $2,000$ notes of ₹200, $3,000$ notes of ₹50 and $5,000$ notes of ₹10.
