6079058.246

Step-by-step explanation:

This is annuity due problem, where the payment is made at the beginning of the year. Here, also the payment is made immediately.

Now, applying Annuity due formula

PV = A (1 - (1+i) ^-n) / i * (1+i)

So, PV is present value of Grand. That is what we want to find

A = annuity (the yearly payment) in this case, it is 500,000

i = is interest rate which is 6%

n = number of years, 20 years

putting all these values in the formula

PV=500,000 (1 - (1+0.06) ^-20) / 0.06 * (1+0.06)

we get 6,079,058.246

This is what the grand price of 10 M worth today.
