Tony runs to keep fit. He wants to run a total of 20 km each week. Here are the

IgorLugansk [536]

Answer:

Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.

Step-by-step explanation:

Distance Tony ran last week are

6.25 km

4 km 750 m

872 km (<em>Note: This would be 8 </em> $\frac{1}{2}$ <em> km and not 872 km</em>)

We will add all the distances to check if they sum up to 20km or not.

First we will convert 4 km 750 m into km

We know that 1000 m = 1 km

So, 1 m = 1/1000 km

750 m = 750/1000 = 0.75 km

Now 4km + 0.75 km = 4.75 km

So, 4 km 750 m = 4.75 km

and 8 $\frac{1}{2}$ km = 8.5 km

Now, finding Distance covered by Tony during last week = 6.25 km + 4.75 km + 8.5 km

= 19.5 km

So, Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.

A TV and Washing machine were purchased for Rs 15000 each. If together, they are sold at Rs 35000, What is Profit and Profit%

Citrus2011 [14]

Given:

A TV and Washing machine were purchased for Rs 15000 each.

Together, they are sold at Rs 35000.

To find:

The profit and profit%.

Solution:

A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is

$C.P.=15000+15000$

$C.P.=30000$

Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.

Now,

$Profit=S.P.-C.P.$

$Profit=35000-30000$

$Profit=5000$

And,

$Profit\%=\dfrac{Profit}{C.P.}\times 100$

$Profit\%=\dfrac{5000}{30000}\times 100$

$Profit\%=\dfrac{50}{3}$

$Profit\%\approx 16.67$

Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.
