At what time the sum Rs. 5000 will be doubled at the interest<br>of 10% per annum?

FromTheMoon [43]

Answer:

Time= $10$ years

Step-by-step explanation:

Let total time $=t$

Initial Amount $=5000$

Final Amount $=10000$

Total interest = Final Amount - Initial Amount

$=10000-5000\\=5000$

Simple Interest $=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years$

Assume that y varies inversely with x. If y=7 when x=2/3, find y when x=7/3

Alinara [238K]

When y varies inversely with x, we have $y= \frac{k}{x}$

We first find the value of k

When y = 7 and x = 2/3, then

$y= \frac{k}{x}$
$7= \frac{k}{ \frac{2}{3} }$
$7( \frac{2}{3})=k$
$k= \frac{14}{3}$

Now we have k = 14/3, we can work out y when x = 7/3

$y= \frac{k}{x}$
$y= \frac{14/3}{7/3}$
$y= \frac{14}{7}$
$y=2$
