Question

Find the amount for principal =Rs 400,
Rate of interest - 5% ,Time period = 3 years​

Answer 1

Answer:

SOLUTION:

Given :

Principal (P) = Rs 400

Rate of Interest (R) = 5% per annum

Time (T) = 3 years

To be found :

Simple Interest (S.I) and Amount (A)

So,

\bf Simple\:\:Interest = \frac{P\times R \times T}{100}SimpleInterest=

100

P×R×T

\bf Simple\:\:Interest = \frac{400\times 5 \times 3}{100}SimpleInterest=

100

400×5×3

\bf Simple\:\:Interest =60SimpleInterest=60

We got Simple Interest (S.I) = Rs 60

Now

Amount (A) = Simple Interest (S.I) + Principal (P)

Amount (A) = Rs 60 + Rs 400

Amount (A) = Rs 460

Hence,

Simple Interest (S.I) = Rs 60

Amount (A) = Rs 460

Answer 2

Answer:

first we have to find S. I.

S. I. =P*R*T

₹400*5/100*3yrs

₹60

to find amount we have to add S. I. to principal

therefore,

₹400+60

₹460
