Answer:
Option (C)
Step-by-step explanation:
From the circle graph attached,
14158428 students have been divided into the sectors of a circle which represent the most important problems for the high school teenagers.
Each sector corresponds the percent of different problem.
Red sector (22% of the total students) represents the most important problem of drugs.
14158428 students ≈ 14000000
22% ≈ 20%
Now 20% of 14000000 high school students = 14000000×
= 2800000
Therefore, Option (C) will be the answer.

Given:
The first two terms in an arithmetic progression are -2 and 5.
The last term in the progression is the only number in the progression that is greater than 200.
To find:
The sum of all the terms in the progression.
Solution:
We have,
First term :
Common difference :
nth term of an A.P. is
where, a is first term and d is common difference.
According to the equation, .
Divide both sides by 7.
Add 1 on both sides.
So, least possible integer value is 30. It means, A.P. has 30 term.
Sum of n terms of an A.P. is
Substituting n=30, a=-2 and d=7, we get
Therefore, the sum of all the terms in the progression is 2985.
