Answer 1

Answer:

option D

Step-by-step explanation:

in a shoe store survey there are 200 customers.

given in the table is that people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.

We have been asked what percentage of people have basketball shoes.

People having basket ball shoes = 0.23 × 200 + 0.31 ×200

                                                       = 108

percentage of people wearing basket ball shoe = $\dfrac{108}{200}\times 100$

= 54 %

we can also find it by directly adding the given value and multiplying it by 100

= 0.23+0.31 = 0.54 ×100 = 54%

hence, the correct answer is option D
