In a poultry farm, 2,000 birds were laying an average of 1,680 eggs per day. Use this information to answer the question
If an egg tray contains 30 eggs, how many trays of eggs will be collected in one week?
240
526
286
392
Correct answer is D
Total number of birds = 2,000
Number of eggs laid per day = 1,680
Number of eggs laid in 7days = 1,680 x 7 =11760
Number of eggs in one tray = 30
x =11760/30
=392 trays
In a poultry farm, 2,000 birds were laying an average of 1,680 eggs per day. Use this information to answer the question
What is the percentage of birds that did not lay eggs?
16%
84%
19%
46%
Correct answer is A
Number of birds that did not lay eggs = Total number of birds - Number of eggs laid
Given information:
Total number of birds = 2,000
Number of eggs laid = 1,680 per day
Number of birds that did not lay eggs = 2,000 - 1,680 = 320
Now, we can calculate the percentage of birds that did not lay eggs:
Percentage of birds that did not lay eggs = (Number of birds that did not lay eggs / Total number of birds) x 100
Percentage of birds that did not lay eggs = (320 / 2,000) x 100 = 0.16 x 100 = 16%
Therefore, the percentage of birds that did not lay eggs on that particular day is 16%.
