A 100 rupee note was changed to 10 and 5 rupee notes, 15 notes in all. How many of each notes?​
san4es73 [151]

Answer:

Total number of notes is 11.

Step-by-step explanation:

Value is 100 rupees…

5x + 20y = 100 and x + y = 11 are the two equations.

We can simplify…

5x + 20 y - 5x - 5y = 100 - 55 = 45

15y = 45 so y = 3

x = 11 - y = 8

So, we have 8 notes of 5 rupees denomination and 3 notes of 20 rupees denomination.

I hope it helps you.

Dennis_Churaev [7]

Answer:

first, u need to know the formula for compound interest, which is:

A = P(1 + \frac{r}{100})^{n}

where A is the final amount

P- initial amount

r- percent compounded(interest)

and

n- number of years

so

we have

A = 475(1 + \frac{3.8}{100})^{4}

3.8/100 = 0.038

1+0.038 =1.038

1.038^4 = 1.160885573136

475 * 1.160885573136 = 551.4206472396‬

approximately $551.42
