Answer:

63731  is your answer

please mark it brainlist

Step-by-step explanation:

simple interest  = p*r*t/100

                         = (63100*10*2)/100

                            = 12620

compund interest = p*(r/100+1) ^t

                                 =63100(10/100+1)^2

                               = 63100(1.1)^2

                                  =76351

difference in simple and compound interest = 76351-12620

                                                                         =  63731

$\Huge\boxed {r.s=631}$

$\Large{\textsf{\textbf{\underline{\underline{Given\::}}}}}$

$p = rs.63100$

$r = 10\%p.a.$

$t = 2 \: years.$

$●diffrence \: between \\ \: ci \: and \: si$

$\Large{\textsf{\textbf{\underline{\underline{formulas.used\::}}}}}$

$si = \frac{prt}{100}$

$A = p \: (1 + \frac{r}{100} )t$

$c.i = a-p$

$\Large{\textsf{\textbf{\underline{\underline{solusion\::}}}}}$

${\bf{1.case\::}}$

$➣to \: find \: s.i.$

$➣we \: know, \:$

$➣s.i. = \frac{p \times r \times t}{100}$

$➣s.i. = \frac{63100 \times 10 \times 2}{100}$

$\small{\textsf{\textbf{\underline{\underline{ ➣s.i = 12620\::}}}}}$

${\bf{2.case\::}}$

$➣to \: find \: ci,$

$➣we \: know, \:$

$➣A = p(1 + \frac{r}{100} )t$

$➣a = 63100(1 + \frac{10}{100} ) {}^{2}$

$➣a = 63100(100 + \frac{10}{100} ) {}^{2}$

$➣a = 63100( \frac{110}{100} ) {}^{2}$

$➣a = 63100 \times \frac{110}{100} \times \frac{110}{100}$

$\small{\textsf{\textbf{\underline{\underline{➣A = 76351\::}}}}}$

${\bf{3.case\::}}$

$➣to.find.c.i$

$➣we.know. c.i = A - p$

$➣c.i = 76351 - 63100$

$\small{\textsf{\textbf{\underline{\underline{➣c.i = 13251\::}}}}}$

$\small{\textsf{\textbf{\underline{\underline{now.finding.the.diffrence.between.ci.and.si\::}}}}}$

$➣c.i = 13251$

$➣s.i = 12620$

$➣difference = r.s (13251 - 12620)$
