B. $100 C.$1,050

Amount = P + (P *n * r)/100
= 1000 + ( 1000*5*2)/100
= 1100$Choice D Thanks Sent from my Lenovo K33a42 using GMAT Club Forum mobile app _________________ IMPOSSIBLE IS JUST AN OPINION GMAT Club Legend Joined: 18 Aug 2017 Posts: 5325 Location: India Concentration: Sustainability, Marketing GPA: 4 WE: Marketing (Energy and Utilities) Re: What is the final balance of a bank account after two years if the sta [#permalink] ### Show Tags 29 Oct 2018, 04:44 What is the final balance of a bank account after two years if the starting balance is$1,000 at an annual rate of 5%, using simple interest?

E. $1,150 $$SI = \frac{1000*2*5}{100}$$ So, $$SI = 100$$ Thus, Amount available at the end of 2 years is$1,100 , Answer must be (D)

Solution

Given:
• Starting balance = $1,000 • Annual rate of simple interest = 5% • No other money was withdrawn or deposited To find: • The final balance after two years Approach and Working: • Balance at the end of 1 year =$1,000 + 5% of $1,000 =$1,000 + $50 =$1,050
• Balance at the end of two years = $1,050 + 5% of 1,000 =$1,100

Hence, the correct answer is Option D
