Let the amount to be invested today be X
Deposit today X
At the end of 1st year = X*1.1 = 1.1X
___
Withdraw 25,000 at the start of 2nd year
Balance at the end of 2nd year
=> (1.1X - 25,000) * 1.1
=> 1.21X - 27,500
___
Withdraw 3,000 at the beginning of 3rd year
Balance at the end of 3rd year
=> (1.21X - 27,500 -3,000) * 1.1
=> 1.331X -33,500
___
Deposit 1,000 in the beginning of 4th year
Balance at the end of 4th year
=> (1.331X - 33,500 + 1,000) * 1.1
=> 1.4641 X -35,805
___
At the start of the 5th year, balance must be 5,000
=> 1.4641X - 35,850 = 5,000
=> 1.4641X = 5,000 + 35,805
=> X = 40,805 / 1.4641
=> X= $27.870.36
So the initial deposit is $27,870.36
