Question

Lakshmi is a cashier in a bank. She has currency notes of denominations Rs. 100,
Rs.50 and Rs. 10 respectively. The ratio of the number of these notes is 2:3:5. The
total cash with Lakshmi is Rs. 400000. How many notes of each denomination
does she have ?

Answer 1

Answer:

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..

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

${\huge{\fcolorbox{cyan}{lime}{\fcolorbox{yellow}{blue}{\sf{\color{yellow}{Answer:- }}}}}}</p><p>$

Let the number of notes of different denomination be x.

∴ Numbers of Rs100 notes, 50 notes and Rs10 notes will be 2x,3x and 5x respectively.

Amount of 100 Rs notes ⇒Rs100×2x=200x

Amount of 50 Rs notes ⇒Rs50×3x=150x

Amount of 10 Rs notes ⇒Rs10×5x=50x

As per the question

Total amount =400000

200x+150x+50x=400000

400x=400000,x=1000

No of Rs 100 notes =2x=2×1000=2000

No of Rs 50 notes =3x=3×1000=3000

No of Rs 10 notes =5x=5×1000=5000
