Question

Raj borrows Rs. 8000: out of which Rs. 4500 at 5% and reminder at 6%. Find the total interest paid by him in 4 years.

Answer 1

Total sum borrowed by Raj= Rs. 8000
In the First Case:
P=Rs. 4500
R= 5%
T= 4 years
$S.I=\frac{P\times R\times T}{100}$
=Rs. \frac{4500 \times 5 \times 4}{100} \)
=Rs. 900
In the second Case:
P= Rs. 8000 -Rs. 4500
=Rs. 3500
R=6%
T=4 years
$S.I=\frac{P\times T\times R}{100}$
$=Rs.\frac{3500\times 6\times 4}{100}$
= $Rs.\frac{3500\times 6\times 4}{100}$
$=35\times 6\times 4=Rs.840$
Total interest paid by Raj =Rs. 900 + Rs. 840
=Rs. 1740
