Question

find total interest when principal =₹1 50 000 rate of interest =11p.c.p.a and time 4=years​

Answer 1

Answer:

Interest=77710.5615

Step-by-step explanation:

compound amount =

$p{(1 \ + \frac{r}{100} ) }^{t}$

so p=150000

t=4

r=11

so as per formula

$150000({1 + \frac{11}{100}) }^{4}$

$150000 {( \frac{111}{100} )}^{4}$

$150000 \times \frac{111}{100} \times \frac{111}{100} \times \frac{111}{100} \times \frac{111}{100}$

$\frac{15 \times 111 \times 111 \times 111 \times 111}{100 \times 100}$

$\frac{2277105615}{10000}$

$227710.5615$

interest = A-P

=227710.5615-150000

=77710.5615
