Answer with Step-by-step explanation:

Khairul deposited $600 in a bank at the end of 2010 at the rate of 3 % per annum simple interest.

simple interest=

where P is the principal amount

r is the interest rate and t is the time

interest got till the end of 2011=

                                                 = $ 18

Khairul deposited $400 in the same bank at the end of 2011.

At the end of 2011 total amount in his bank= $(600+18+400)

                                                                       = $1018

Interest he got from end of 2011 till end of 2013=

                                                 = $ 61.08

Total amount in his bank at the end of 2013=$(1018+61.08)

                                                                        = $ 1079.08

Hence, total amount Khairul has in his bank at the end of 2013 is:

$ 1079.08
