CAT Exam

In a ballot process, 900 votes more were polled in favour of a resolution than were polled against it. It was also noticed that the number of votes polled against the resolution was 30 percent of the total number of votes polled. If all the votes polled were valid and each vote was either in favour of the resolution or against it, find the total number of votes polled.

Read Solution (Total 2)

total votes = 2250

x*0.7 = x*0.3 +900
0.4x =900
x= 2250

suppose candidate 1 receive x vote
n candidate 2 receive x+900
so total vote =2x+900

so 900 is 40% of total voe
so total votes are 900*100/40=2250
