(1). The compounded intrest on this sum for one year payable half-yearly at the same rate.

Answer 1

Answer:

principal is x

time is 2years

rate of interest is12%

SP is ₹1380

x × 2×12/100 =1380

x= (100×1380)/2×12

x= 138000/24

x=5750

1) p=5750

r=12/2=6

t=1/2

amount=5750{1+6/100}*2

5750×8×8/5×5

368000/25

amount=14720

compound interest=14720-5750

8970
