Option C is the correct answer.
Before answering the question lets understand the given information. So the question tells us at in a company wide voting for two projects each employee has taken part in this voting and every one has voted for only one of the two projects. Then it tells us that Project X received 20% more votes than Project Y, Finally tell us that Project Y received total 70 votes and then ask us about the vote difference between Project X & Project Y.
Lets solve for the answer now:
Lets take vote percentage of Project Y to be 'A' then for Project X it will be 'A+20'
so, Vote percent of Project Y + Vote percent of Project X = 100
A + A + 20 = 100
2A = 80
A = 40%
Vote percent of Project Y = 40%
Vote percent of Project X = 40 + 20 = 60%
Now we know that Project Y has 40% vote share and has received a total of 70 votes. So from here we can calculate the total number of votes casted by all the employees in the company. Lets take total number of votes to be 'V'.
So, Vote for Project Y = 70
40%*(V) = 70
(40/100)*(V) = 70
V = 70*(100/40)
V = 175
Now lets calculate Votes for Project X.
Votes for Project X = 60% of 175
=(60/100)*175
=105
Now the question asks us about the vote difference between the projects or by how many votes does Project Y lose
Vote Difference = Votes for Project X - Vote for Project Y
= 105 - 70
=
