In a market survey, 20% opted for product A whereas 60% opted for product B. The remaining individuals were not certain. If the difference between those who opted for product B and those who were uncertain was 720, how many individuals were covered in the survey ?

a. 3600
b. 1440
c. 1800
d. Data inadequate

Read Solution (Total 2)

Ans:C

A=20%
B=60%
Therefore Uncertain=100-(60+20)=20%
Diff bw B and uncertain=720
so Uncertain(%=amt)
ie.(720/20)*100=1800
