Hi Gunner77 and tinuviel07,
There is nothing wrong with the question but the answer given is incorrect. This question is an actual past "O" level E. Maths exam question. However, the answer given by the publisher is wrong. The correct answer is $20,606.02.
Method 1 : This method is commonly used by E. Maths students
Amount at end of 1st month
= $20000 + 0.01 x $20000 = $20,200
Amount at end of 2nd month
= $20,200 + 0.01 x $20,200 = $20,402
Amount at end of 3rd month
= $20,402 + 0.01 x $20,402 = $20,606.02
Method 2 : Short-cut Method
Amount at end of 3rd month
Amount at end of 3rd month
= (1.01)^3 X $20,000 = $20,606.02
Thank you for your kind attention.

Hi tinuviel07,
There is another actual past "O" level E. Maths question that requires even more working ie an amount is deposited at a compound interest of 10% per annum for 3 years, at the end of the 3rd year, there is $532.40 in the account, what is the original amount deposited ?
So, please help him to learn both methods. Ok.
