Answers
Answer:
given,
rate of decreasing=12%
decreased money=2640
time=2 year
a/q
decreased money=p- p(1-r/100)^n
2640=p -p(1-12/100)²
2640=p -p(88/100)²
2640=p-p(22/25)²
2640=p-p(484/625)
2640=484p/625
2640=141p/625
2640×625=141p
1650000=141p
1650000/141=p
11702.12766=p
answer will be 125000 if it is decreases. by 5640
5640=484p/625
5640=141p/625
5640×625=141p
3525000 =141p
3525000/141=p
125000=p
