Answer 1

40000*105/100=42000 будет через год
42000*105/100=44100 будет через 2 года
44100*105/100=46305 через 3 года 

Answer 2

Calculating Interest on Deposit

To calculate the amount on the depositor's account after one, two, and three years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where: - A = the amount of money accumulated after n years, including interest. - P = the principal amount (initial deposit). - r = the annual interest rate (in decimal). - n = the number of times that interest is compounded per year. - t = the time the money is invested for in years.

Calculation

Given: - P = 40,000 (principal amount) - r = 5% or 0.05 (annual interest rate) - n = 1 (compounded annually)

# After One Year:

A = 40,000(1 + 0.05/1)^(1*1) A = 40,000(1.05) A ≈ 42,000

# After Two Years:

A = 40,000(1 + 0.05/1)^(1*2) A = 40,000(1.05)^2 A ≈ 44,100

# After Three Years:

A = 40,000(1 + 0.05/1)^(1*3) A = 40,000(1.05)^3 A ≈ 46,305

So, the amount on the depositor's account after one year will be approximately 42,000 rubles, after two years will be approximately 44,100 rubles, and after three years will be approximately 46,305 rubles.
