Question

the sum of rs 12500 and interest rate is 4% per annum for 2 years compounded annually. find the compound interest.​

Answer 1

Step-by-step explanation:

+4%

+4/100

+1/25

26/25

time is 2year

so principal = 25²=625

amount = 26²= 676

625=12500

1= 20

676= 20×676

676= 13520

hence amount is 13,520

#666

Answer 2

Answer:

1020

Step-by-step explanation:

rate = 4% = 4÷100 =1/25

12500×1/25 = 500, 500×2 = 1000

500×1/25 = 20, 20×1 = 20

( hint: for 2 years multiply with 2 & 1

for 3 years multiply with 3,3 & 1 )

compound interest = 1000+20 = 1020

total amount = 12500+1020 = 13520
