The students of a school were asked to name their favorite type of pet. Of the 430 students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 150 students were surveyed, with similar results, about how many students would say that a dog is their favorite type of pet?

Question: The students of a school were asked to name their favorite type of pet. Of the 430 students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 150 students were surveyed, with similar results, about how many students would say that a dog is their favorite type of pet?

Solution:
Given that,
Out of 430 students, 258 students chose dog.
Fraction = 258/430
= 3/5

So, if 150 students are surveyed, the number who would choose dog = 150 × (3/5)
= 90

Correct Answer: খ) 90
