In a certain town, 25% families own a cell phone, 15% families own a scooter and 65%
families own neither a cell phone nor a scooter. If 1500 families own both a cell phone
and a scooter, then the total number of families in the town is
1) 10000
2) 20000
3) 30000 4) 50000​

Answer 1

Answer:

n(c) = 25%

n(s)= 15%

n(c or s )'= 65%

so,n(c or s) = 100%-65%m

= 35%

n(c and s) = 1500

n(c and s) = n(s) + n(c) - n(c or s)

1500. = 25%+15% -35%

1500. = 5%

5% =. 1500

100%. =. ?

= (1500×100)/5

= 30000
