Answer:
sum = 4096
Step-by-step explanation:
some amount of money grows up to 8000 in 3year and up to 10000 in 4year
on compound intrest what is sum
Let say Sum = P
8000 = P(1 + R/100)³
10000 = P(1 + R/100)⁴
On Diving
1 + R/100= 10000/8000
1 + R/100 = 5/4
=> R/100 = 1/4
=> R = 25 %
8000 = P(1 + R/100)³
=> 8000 = P ( 1.25)³
=> P = 4096
sum = 4096
