Question

2. In a purse there are notes of denomination Rs. 50, Rs. 100 and Rs. 500 only in the ratio
of 1:2:3 respectively. If the total amount in the purse is Rs. 10,500, how many Rs. 100
notes are there in it?​

Answer 1

Answer:

12 notes.

Step-by-step explanation:

Let the no. of notes be 1x, 2x and 3x

Now,

Value of Rs.50=

$50 \times x = 50x$

Value of Rs.100=

$100 \times 2x = 200x$

Value of Rs.500=

$500 \times 3x = 1500x$

Now, according to question

sum of money= Rs. 10,500

$50x + 200x + 1500x = 10500$

$250x + 1500x = 10500$

$1750x = 10500$

$x = \frac{10500}{1750}$

So,

$x = 6$

Now, we have to find number of notes of Rs.100,

100= 2x

= 2×6

=12 notes Ans.
