Question

Saransh had $26,000 in denominations of $100 $50 and $ 10 in the ratio 2:5:7. How many notes of each dose he have?

Answer 1

Let the number of notes be X

Now, multiply the denominations by there ratios

100 × 2 = 200

50 × 5 = 250

10 × 7 = 70

Now,

no. of 100$ notes = 200x

no. of 50$ notes = 250x

no. of 10$ notes = 70x

Now,

200x + 250x + 70x = 26000

520x = 26000

x = 26000/520

x = 50

Now, by putting the value of x, we get

200x = 200 × 50 = 10,000

250x = 250 × 50 = 12,500

70x = 70 × 50 = 3,500

Hence, Saransh have,

10,000 notes of 100$,

12,500 notes of 50$, and

3,500 notes of 10$.
