• Number of 5 ruppes notes =210

• Number of 10 rupees notes = 336

Given :

• Praveen has rupees 4662 in the from of 2 and 5, 10 rupees notes.

• These notes are in the ratio of 3:5:8.

To find :

• The number of five rupees notes within him =?

Step-by-step explanation:

Let number of 2 rupees notes =3x

Then, number of 5 rupees notes=5x

And, number of 10 rupees notes =8x

According to the question :

2(3x)+5(5x)+10(8x)=4662

6x+25x+80x=4662

111x=4662

x = 4662/111

x = 42

Hence,

• Number of 2 rupees notes, 3x = 3×42=126

• Number of 5 ruppes notes, 5x =5×42=210

• Number of 10 rupees notes,8x= 8×42=336

Answer 2

Given :

Total rupees praveen has = Rs. 4662

In which there were 2 , 5 and 10 Rupees notes.

Assuming the notes are in ratio of 3:5:8

To find :

Total no. of Rs. 5 notes

Solution:

Let x to be included in the ratio then 3x , 5x and 8x

Let the no. of Rs 2 , Rs 5 and Rs 10 be 3x , 5x and 8x

Now According to question,

3x × 2 + 5x × 5 + 10x × 8 = Rs. 4662

= 6x + 25x + 80x = Rs.4662

= 111x = Rs. 4662

=> x = Rs. 4662/111

x = Rs. 42

Now finding the no. of all Rs. 2 , Rs. 5 and Rs.10 notes

No. of Rs.2 notes = 3× 42 = 126

No. of Rs.5 notes = 5 × 42 = 210

No. of Rs.10 notes = 8 × 42= 336

In question, it is asking the no. of only Rs. 5 notes

= 210
