Answer:

18. D 80%

19. b. 10%

20. b. 10000

Step-by-step explanation:

18. On Sunday total no of peple visited zoo = 845

On Monday total no of people visited zoo = 169

Decrease = 845 – 169                    

                 = 676

Percentage = (676 / 845 ) * 100                        

                  = 0.8 * 100                    

                  = 80 %

19. Given that cost price = 750 rupees.

We assume here that cost of 750 do not include the overhead expenses of 50 rupees.

Hence we add this to cost to get total cost.

Overhead expenses = 50 Rs.

Hence total cost expenses = 750+50 = 800 rupees

Profit = 80 rupees

When there is a profit there is a gain only.  

Here gain = 80 out of 800

Hence gain percentage = 80/800 % = 10%

20. We know that when there is an overhead charge it must be added to the Cost price.

So, Total Cost price

= 46,000 + OC

=  46,000 + 4,000

= 50,000

Since, SP > CP

There is a Gain.

Gain or Profit = SP - CP

                      = 60,000 - 50000 = 10,000

∴ The Gain is 10,000.

Gain% = Gain/ CP * 100

=  10,000/50,000 * 100

= 20%

History (from Greek ἱστορία, historia, meaning "inquiry; knowledge acquired by investigation") is the study of the past. Events occurring before the invention of writing systems are considered prehistory. "History" is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Historians place the past in context using historical sources such as written documents, oral accounts, ecological markers, and material objects including art and artifacts.
