A fruit seller purchased 20 kg of apples at Rs 80 per kg and sold them at Rs 85 per kg. find profit and profit percent​

Answers

Answer:

Profit = Rs 100

Profit %age = 6.25%

Step-by-step explanation:

Cost Price = Rs 80

Cost Price for 20 kg = Rs 1600

Selling Price = Rs 85

Profit for 1 kg = Rs 85 - Rs 80

=> Rs 5 (For 1 Kg)

Profit for 20 kg:

=> Rs 5*20

=> Rs 100

Now Profit %age:

=> (100)/(1600)* 100

=> 0.0625 * 100

=> 6.25%

Step-by-step explanation:

profit =S.P-C.P

C.P=20×80

=Rs1600

S.P=20×85

=Rs1700

=1700-1600

=Rs 100

If an automobile travels 450 yards in 15 seconds, how many feet does it travel in 1/3 of a second?how do I calculate this problem?

Answers

You can calculate it from the formula for velocity
v=(s)/(t)
if it travels 450 yards in 15 seconds
s=450 yards t= 15s
1 yard = 3 feet so
s= 1350 feet
v=(1350)/(15)=90 (feet)/(s)
so if in one second it travels 90 feet, in (1)/(3) of a second it travels (90)/(3) =30 feet

4. The point

5 1/3 units from A and

2/3

units from B

Answers

Given :

A point x whose distance from A is 5 1/3 units.

distance between x and B is 2/3 units.

To Find :

Distance between A and B if they both are on left side of straight line from x.

Solution :

Let distance between A and B is d :

d=|A-B|\n\nd=|5(1)/(3)-(2)/(3)|\n\nd=|(16)/(3)-(2)/(3)|\n\nd=(14)/(3)\n\nd=4(2)/(3)\ units

Therefore, distance between A and B is 4 2/3 units.

Hence, this is the required solution.
