ratio = a:b:c=4:3:1
but c =2 million
thus multiplying the ratio with 2 we get = 8:6:2
thus total = 16 million
As 16 million is 20% decreased value of total X(let) voters
16 = X(1-20/100)
thus X= 20 million
thus number of people not voted = 20-16 million =4 million

Ans D

Let , Total Voters be 100
No of Voters who didn't cast their votes is 20
No of Voters who casted their votes is 80

Voters received by A:B:C = 40 : 30 : 10

It is 10 represents 2 million people
So, 1 represents 2/10 million people
And 100 represents 2/10*100 = 20million people

Voters who didn't cast their votes is 20% of 20 million people = 4 million people...

Answer will hence be (D) 4 million..

Hey,

PFB the official solution.

Working Out:

    • Let the total number of votes = T
    • As 20% of the total voters refrained from voting,
      o 100% -20% = 80% of voters voted
      o Therefore, the total number of people who voted = 80% of T = 0.8 x T
    • Candidates A, B and C received votes in the ratio 4 :3: 1 respectively means
      o Number of votes received by Candidate A = 4X
      o Number of votes received by Candidate B = 3X
      o Number of votes received by Candidate C = 1X

Drawing the tree structure, we get



From the tree structure,

    • People who voted = 0.8T = 4X + 3X + 1X
    • 0.8T = 8X = 8 x 2 million
    • 0.8T = 16 million
    • T = 20 million

People who refrained from voting
    • 0.2T
    • 0.2 x 20 million
    • 4 million

Correct Answer: Option D
