Answer:

$\sqrt{98}$ or 9.89949

Step-by-step explanation:

use the distance formula

d= $\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1})^{2} }$

d= $\sqrt{(-5-2)^{2}+(8-1)^{2} }$

d= $\sqrt{(-7)^{2} +(7)^{2} } \\\\\sqrt{49+49}$

d= $\sqrt{98}$ or 9.89949

Answer: Loss, 200 Rs

Step-by-step explanation:

Given

Sharad bought a quintal of onion i.e. $1000\ kg$ for $Rs.\ 2000$

So, the cost price of onion is

$\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}$

He sells it at $18\ \text{Rs. per kg}$

Here, the Selling price is less than the cost price

So, he incurs a loss of $2\ \text{Rs per kg}$

For a quintal it is

$\Rightarrow 2\times 100=200\ \text{Rs}$

$\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%$
