Question

kate has some notes of denominations Rs 20 and Rs 50. The number of Rs 20 notes is twice the number of Rs 50 notes. If the amount with her is Rs 300 more than five times the number of notes, find the number of notes of each denomination with her

Answer 1

Answer:

The no. of notes of Rs. 50 is 4 and The no. of 20 rupees notes is 8.

Step-by-step explanation:

Let the no. of notes of Rs. 50 be x

Amount of x notes of Rs. 50 = 50x

We are given that The number of Rs 20 notes is twice the number of Rs 50 notes.

So, The no. of 20 rupees notes = 2x

Amount of 2x notes of Rs. 20 = 40x

Total no. of notes = 2x+x=3x

Now we are given that the amount with her is Rs 300 more than five times the number of notes,

$50x+40x=300+5(3x)$

$90x=300+15x$

$75x=300$

$x=4$

So, the no. of notes of Rs. 50 =4

The no. of 20 rupees notes = 2x = 2(4)=8

Hence the no. of notes of Rs. 50 is 4 and The no. of 20 rupees notes is 8.
