Explanation / Answer

given question is:-

SavingsAccount b = new SavingsAccount (10);

b.deposit (5000);

b.withdraw (b.getBalance () / 2);

b.addInterest ();

-----------

initially when

SavingsAccount b = new SavingsAccount (10);

//** here balance is initially zero

now in next code

b.deposit (5000);

//** here balance value becomes 5000

b.withdraw (b.getBalance () / 2);

//** here balance =5000/2,which is equal to 2500,since half of the deposited amout in withdrawn,therefore we are left with only 2500,so now the further process wiill carry using 2500.

b.addInterest ();

//**here after adding interest,the balance value becomes 2750,this interest is from the 10%of 2500=250

no when we add 2500+250=2750

so the final value of b=2750.
