(3 A sum of money doubles itself in 6 years. In how many years, it becomes 5 times?

elena-s [515]

Answer:

In 24 years.

Step-by-step explanation:

Let the sum of money be 100 which amounts to 200 ( doubles itself ) in 6 years time. Interest on 100rs. Is 100. Putting the following in simple interest formula. You get :

$100=\dfrac{100\times R\times 6}{100}\\\\R=\dfrac{100}{6}$

Now when 100 will become 5 times i.e 500 the interest will be 400rs.

Putting in simple interest formula:

$400=\dfrac{\dfrac{100\times 100}{6T}}{100}\\\\T=\dfrac{2400}{100}\\\\=24\ yrs$

So, in 24 years, it will become 5 times.

PilotLPTM [1.2K]

57,800 is 23.8% of the total number of registered doctors.

To find out the number of registered doctors, we divide the number of female doctors by 23.8% as a decimal (which is just 0.238):

57,800 ÷ 0.238 = 242,857
-------------------------------------------------------------------------------------------------------------
Answer:

So there are 242,857 registered doctors.

Answer:

Step-by-step explanation:

a) (5,5) ; (10,6); slope = 1/5

(x1,y2); (x2,y2)

y-y1 = m (x-x1)

$y-5=\frac{1}{5}*(x-5)\\\\y-5=\frac{1}{5}*x-\frac{1}{5}*5\\\\y-5=\frac{1}{5}x-1\\y=\frac{1}{5}x-1+5\\\\y=\frac{1}{5}x+4$

d) (√2,7) ; (√2,-7)

(x1,y1) ; (x2,y2)

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-7-7}{\sqrt{2}-\sqrt{2}}\\\\=\frac{-14}{0}=0$

Equation: y =7 or y = -7
