Question

ii) Principal = Rs 500,
and Time = 5 years.
Rate of Interest = 12.5% per annum and Time = 4 years.

Answer 1

PRINCIPAL = ₹ 500

And TIME = 5 YEARS

RATE OF INTEREST = 12.5% P.A.

TIME = 4 YEARS

SIMPLE INTEREST = P× R × T / 100

=500×5×12.5×4/100

=1,25,000/100

= 1250

:. Simple Interest = 1,250

Answer 2

Answer:

P= 500,Rate of Interest=12.5% per annum, Time=4years

Now, Interest rate= 12.5% per annum

Interest on Rs 100 for one year = Rs 12.5

Therefore, Interest on Rs 100 for 4years= (12.5x4)= Rs 50

Interest on Rs 1 for 4years= Rs 50/100

Hence, Interest on Rs 500 for 4years= Rs 50/100x500= Rs 250

We have,

P=Rs 500, Rate of Interest = 12.5% per annum, Time = 4years

Let I be the interest. Then,

I= PRT/100= I = Rs [500x12.5x4/100]= Rs (50x5)

= ( 50x5) = Rs 250 is the answer
