Question

A survey is conducted with a random sample at multiple places in the city as shown to analyze the preference of fruits among the people.

From the population size of 400, estimate the total number of people who prefer mango.

• A. 140
• B. 160
• C. 100
• D. 70

Answer 1

The correct option is A 140

In the given sample,

Here,
Sample size = 50 + 80 + 70 = 200

Number of people who prefer mango = 70
Percentage of people who prefer mango is:
$=\frac{70}{200}\times 100\%=35\%$

Number of people who prefer mango $=\text{Percentage of people prefering mango}\times \text{population size}=\frac{35}{100}\times 400=140$

$\therefore$ Total number of people who prefer mango in the city are 140.
