5440.

If simple interest and compound interest of a certain sum of money for two years are RS. 8400 and RS. 8652 ,then find the sum of money and the rate of interest.

Answer»

$\sf\small\underline{Let:-}$

$\tt{\implies The\:sum\:of\: money=P}$

$\tt{\implies The\:rate\:of\: interest=r}$

$\sf\small\underline{To\: Find:-}$

$\tt{\implies The\:sum\:and\:rate=?}$

$\sf\small\underline{Solution:-}$

To CALCULATE the sum and rate at first we have to set up equation by applying formula of simple interest and compound interest with the help of GIVEN clue.

$\rm\large\underline{Calculation\:for\:SI:-}$

$\tt\small\underline{Sum=P\:\:T=2years\:\:R=r\:\:SI=Rs.8400:-}$

$\tt{\longrightarrow SI=\dfrac{P*T*R}{100}}$

$\tt{\longrightarrow 8400=\dfrac{P*2*R}{100}}$

$\tt{\longrightarrow 2Pr=840000}$

$\tt{\longrightarrow Pr=420000-----(i)}$

$\rm\large\underline{Calculation\:for\:CI:-}$

$\tt\small\underline{Sum=P\:\:T=2years\:\:R=r\:\:CI=Rs.8652:-}$

$\tt{\longrightarrow CI=P\bigg[1+\dfrac{r}{100}\bigg]^n-P}$

$\tt{\longrightarrow 8652=P\bigg[1+\dfrac{r}{100}\bigg]^2-P}$

$\tt{\longrightarrow 8652=P\bigg[\dfrac{100+r}{100}\bigg]^2-P}$

$\tt{\longrightarrow 8652=P\bigg[\dfrac{10000+200r+r^2}{10000}\bigg]-P}$

$\tt{\longrightarrow 8652=\dfrac{10000P+200Pr+Pr^2}{10000}-P}$

$\tt{\longrightarrow 8652=\dfrac{10000P+200Pr+Pr^2-10000P}{10000}}$

$\tt{\longrightarrow 8652*10000=200Pr+Pr^2}$

$\tt{\longrightarrow 8652*10000=Pr(200+r)----(ii)}$

Substituting the value of Pr = 420000 :-]

$\tt{\longrightarrow 8652*10000=420000(200+r)}$

$\tt{\longrightarrow 8652=42(200+r)}$

$\tt{\longrightarrow (200+r)=8652\div\:42}$

$\tt{\longrightarrow 200+r=206}$

$\tt{\longrightarrow r=206-200}$

$\tt{\longrightarrow r=6\%}$

PUTTING the value of r=6 in eq (i):-]

$\tt{\longrightarrow Pr=420000}$

$\tt{\longrightarrow P(6)=420000}$

$\tt{\longrightarrow P=70000}$

$\sf\large{Hence,}$

$\tt\red{\implies The\:sum\:of\: money=Rs.70000}$

$\tt\blue{\implies The\:rate\:of\: interest=6\%}$

an adult's ticket to a cricket match costs twice as much as a child's ticket.the cost for mr and mrs brown and their 5 children is dollar 3.15. if a child's ticket costs C cents, write an equation to show this information

Answer»

Step-by-step explanation:

let adult ticket be y

and children's ticket be

therefore, y=2x ---- eq(i)

Mrs and Mr BROWN with their children's COST = $3.15

considering that Mrs and Mr Brown are adults.

2y+5x=3.15

after substituting value of y from eq(i) -

we get

2(2x)+5x=3.15

9x=3.15

x=0.35

after GETTING x's value, we can SUBSTITUTE the value of x in eq (i) therefore y=2(0.35)

=0.7

therefore, adult ticket's value = $0.7 or 7€

and children ticket's value = $0.35 or 3.5€
