Given :
All the natural numbers below 1000 that are multiples of 3 or 5 .
To Find :
The sum of all the multiples of 3 or 5 below 1000.
Solution :
Max multiple of 3 is 999 .
Max multiple of 5 id 995 .
So , number of multiple of 3 is :
Similarly for 5 .
Now , sum of all multiple of 3 is given by :
Also , sum of all multiple of 5 is :
Therefore , total sum :
Now , there are some common number which we add two times like :
15 , 30 , 60 ......
So , we should subtract the sum of all multiple of 15 from T .
Now , sum of all multiple of 15 is 33165 .
So ,
Therefore , the sum of all the multiples of 3 or 5 below 1000 is 233168 .
The value of the final deposit is 5000. The value of the one a year previously is 5000*1.1 = 5500. The one previous to that has a value of 5000*1.1^2 = 6050. The first deposit has a value of 5000*1.1^3 = 6655.
The total value of the 4 deposits is
.. 6665 +6050 +5500 +5000 = 23,205
You will have $23,205 just after you make the 4th deposit.
_____
This is the sum of 4 terms of a geometric sequence with common ratio 1.1 and initial value 5000. That can be calculated as
.. a0*(r^n -1)/(r -1)
.. 5000*(1.1^4 -1)/(1.1 -1)
.. = 5000*4.641
.. = 23,205

Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four
generations of selection,
D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
pounds.
