Question

Ravi works as a cashier in a bank. He has currency of denominations Rs. 100, Rs. 50, Rs. 10 respectively. The ratio of the number of these notes is 2 : 3 : 5.

The total cash with Ravi is Rs. 4,00,000.
How many notes of cash of each denominations does he have?

Answer 1

Let the number of $\text{Rs.}100$ notes $=2x$
Number of $\text{Rs.}50$ notes $=3x$
and Number of $\text{Rs.}10$ notes $=5x$
$\therefore$ Total Money $=(2x\times 100)+(3x\times 50)+(5x\times 10)$
$200x+150x+50x=400x$

But according to the problem the total money is $\text{Rs.}4,00,000$
$\Rightarrow$ $400x=4,00,000$
$x=\frac{400000}{400}$

$x=1000$

Therefore, Number of $\text{Rs.}100$ notes $2x=2\times 1000=2000$
Number of $\text{Rs.}50$ notes $=3x=3\times 1000=3000$
Number of $\text{Rs.}10$ notes $=5x=5\times 1000=5000$
