Question

FIND the amount and Compound Interest on rupees 31250 for 2 yrs 6 months at 6 percent per annum compounded anually.

i want answer with solution..​

Answer 1

Answer:

P=Rs. 31250,R=8%,T=2times43,A=?

A=P(1+100R)

⇒31250(1+1008)243

⇒31250×100108×100108×100106

⇒Rs.38637

C.I=A−P

=38637−31250

= Rs.7387 ans.

Thanks..

Answer 2

Answer:-

Given:-

Principle(P)=Rs.31250

Time(T)=2years 6months

$\: \: \: \: \: \: \: \: \: \: \: \: \: =2 \ + \frac{6}{12}$

L.C.M of 12 and 1 is 12.

Now,

$\: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{24 + 6}{12}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{30}{12}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: = 2.5 \: years$

Rate(R)=6%

To Find,

Amount and compoud interest.

Formula To Used:-

$\: \: \: \: \: \: \: \: \: \: \: \: = \frac{468750}{100}$

A=P+I

I=P×T×R÷100

Solution:-

I=P×T×R÷100

$\: \: \: \: \: \: \: \: \: \: \: \: = \frac{31250 \times 2.5 \times 6}{100}$

$\: \: \: \: \: \: \: \: \: \: \: \: = \frac{468750}{100}$

$\: \: \: \: \: \: \: \: \: \: \: \: = 4687.5$

$\\ \sf \implies \bold{\purple{Hence\: Interest\: is =\: Rs.4687.5\: {}^{}}}$

A=P+I

=(31250+4687.5)

=35,937.5

$\\ \sf \implies \bold{\purple{Hence\: Amount\: is =\:Rs.35,937.5\: {}^{}}}$
