Question

John has a total of 1460 as currency notes in the denominations of 50, 320, and 10. The ratio of the
number of 250 notes and 20 notes is 4:3. If he has a total of 70 notes, how many notes of each
denomination he have?
The ratio of the number of 750 notes and 20 notes is 4:3. So, if the number of 50 notes is 4z (where x is a
non-zero integer), the number of 20 can be represented in terms of z as 3.
Now, since there are a total of 70 notes, out of which there are 4 notes of 50 and 3
notes of 20, the
number of notes of €10 is (70- ?)​

Answer 1

Answer:

Step-by-step explanation:

Let teh no. Of 10 and 20 notes be x .

No. Of 20 notes =3x

No. Of 10 notes =4x

Acc. To question -

He has 24 notes .

Hence No. Of 5 notes = 24 - 7x (3x+4x)

Hence

Rupees out of 20 notes = 60x

10 notes = 40x

5 notes = ( 24×5 ) - (7x × 5 )

= 120 - 35x

Hence

Total money = 60x + 40x + (120-35x)

250-120=60x + 40x - 35 x

130 = 65x

x = 2
