C. 274054.18

D. 274074.18

E. None of the above (This answer is incorrect)

Explanation / Answer

Ans 1.

Formula for future value of Annuity :

FV= A [ (1+k)n-1/k]

FV = Future anuuity value

A = periodical investement=$8700

K=interest rate=6% pa

n=periods=21 years

FV= 8700[{(1.06)21-1}/0.06]

=8700(3.4-1)/0.06

=348,000

After 22 years the value will be $348,000

After 24 years the value will be =348,000*1.06*1.06=$391,013

So answer is E.

2.

Formula for future value of Annuity :

FV= A [ (1+k)n-1/k]

FV = Future anuuity value

A = periodical investement=$147 per week

K=interest rate=6.25% pa=0.1198% per week

n=periods=886.42 weeks ( considering 52.14 weeks per year)

So FV= [147{1.0012}886.4-1}/0.0012

=147*1579.17                    

=232,137.50   

Value of $14500 after 17 years = 14500(1.0012)886.4

=14500*2.895

=41,977.50

So, total value of fund=$(232,015+41,963)=$274,115.0

So the answers A to D all are near to the value derived and nearest correct is option D
