Question

The simple interest on a sum of money for 2 years at 10% per annum is rupees 1700 find:1)the sum of money,2)the compound intrest for this sum for 1 year,payable half-yearlyat the same rate.​

Answer 1

Step-by-step explanation:

s.i = 1700

p× 10×2 /100 = 1700

p = Rs 8500

rate = 10% =10/2 = 5% half yearly

time = 1 year = 2 half years

c.i =8500[ (1 + 5/100)^2 - 1]

c.i = 8500[(1.05)^2 - 1]

C.i = Rs 871.25

(1)Sum = Rs8500,(2) c.i = Rs 871.25

Answer 2

Step-by-step explanation:

p=(1700*100)/2*10

=1700*5=8500

p=8500

c.i.

1st half year=8500*10*1/100*2

=425

amount=8500+425=8925

2nd half year=8925*10*1/100*2

=446.25

amount=8925+446.25=9371.25

co=9371.25-8500=871.25
