Question

if rupees 12500 amount to rupees 1550 in 3 years at simple interest what will rupees 3200 amount to in 4 years at the same rate​

Answer 1

Answer:

Simple interest would be Rs. 1024.

Step-by-step explanation:

Since we have given that

Principal = Rs. 1250

Amount = Rs. 1550

Time = 3 years

simple interest = 1550- 1250 = Rs. 300

So, it becomes,

\begin{gathered}S.I.=\dfrac{P\times R\times T}{100}\\\\300=\dfrac{1250\times 3\times R}{100}\\\\30000=1250\times 3R\\\\\dfrac{30000}{3750}=R\\\\R=8\%\end{gathered}

S.I.=

100

P×R×T

300=

100

1250×3×R

30000=1250×3R

3750

30000

=R

R=8%

So, if principal = Rs. 3200

time = 4 years

So, Simple interest would be

\begin{gathered}\dfrac{3200\times 8\times 4}{100}\\\\=32\times 32\\\\=Rs.\ 1024\end{gathered}

100

3200×8×4

=32×32

=Rs. 1024
