Answer 1

Step-by-step explanation:

principal=30,000

time=3years

rate=15%p.a.=3/20(in fraction)

C.I. - S.I.=???

30,000

/. |. \

/. |. \

4500. 4500. 4500[with rate 15%]

(1st yr ). (2nd). (3rd)

\. \

\. \•••••••675[same rate here also

\••••••••••••••••••675

|•••••••••675••••101.25

C.I. - S.I. = 3×675+101.25=2126.25

Answer 2

Answer:

Ci= p{(1+r/100)^n-1}

30000{(1+7/100)^3-1}

30000{(100+7/100)^3-1}

30000{(107/100)^3-1}

30000{1,225,043/1000000-1

30000{1.225043-1}

30000{0.225043}

30000×0.225043

6751.29

Therefore ci = 6751.29

Si= pxrxt/100

30000x7x3/100

=6300

Therefore si =6300

There difference= 6751.29 - 6300=451.29 answer.
