While counting it has been observed that students from all standards except 8th, 9th and 10th have voted for all the three candidates in equal numbers. The students from standard 8 voted for only Dev and Xamim, students from standard 9 did not vote for Dev. The students of standard 10 voted for all of them, however no student voted for both Dev and Praveen. The total number of votes from 8th standard is equal to 140, the number of students from 9th standard who voted for Xamim is 70. The total number of students in standard 10 is 150 out of which the number of students in standard 10 who caste only one vote is 120. The total number of students who caste exactly two votes is 130.

Answer the following question based on the information given below.In ...
The candidates get votes from a class if and only if he campaign in that class.Dev and Praveen did not campaign in 9th and 8th standard respectively. Also, all 3 have campaigned in 10th standard which means that the students of 10th standard did not miss any campaign.

The number of students who were not present for exactly one campaign = Number of students of 9th standard + Number of students of class 8th standard
Let Dev, Praveen and Xamim be denoted by D, P and X respectively
The Venn diagram follows the given table :From the above table following equations can be derived :
a + 2b + c = 140 ... (i)
e+f = 10... (ii)
g + h + i+j + k = 150 ... (iii)
g + i + k = 120 ... (iv)
b + e + h+j = 130 ... (v)
From (iii) and (iv), h+j = 30 ... (vi)
So, from (v) and (vi) b + e = 100 ... (vii)
Subtracting (ii) from (vii), we get b -f= 30
Also, b:f= 4:1 ...[Given] b = 40 and/= 10 Substituting b = 40 in (i), we get a + c = 60
The total number of students in 8th standard = a + b + c = 100 Given that d = 30
The number of students in 9th students = d + e + f= 30 + 70 = 100.
Therefore, the number of students who were not present for exactly one campaign = 100+100 = 200
Hence, option 2
