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?180014403600Data inadequate

The correct option is B 1800Percentage of uncertain individuals =[100−(20+60)]%=20%Since,60% of x−20% of x=72040% of x=720 40100x=720 x=720×10040=1800Hence the answer is 1800.

The correct option is B $1800$
Percentage of uncertain individuals
$= [100 - (20 + 60)] % = 20 %$
Since,
$60 %$ of $x - 20 %$ of $x = 720$
$40 %$ of $x = 720$
$\frac{40}{100} x = 720$
$x = \frac{720 \times 100}{40} = 1800$
Hence the answer is $1800$ .
