Question

A company makes 110 bags. 46 of the bags have buttons but no zips. 20 of the bags have zips but no buttons. 39 of the bags have neither zips nor buttons. How many bags have zips on them?

Answer 1

= 51/110

Explanation:

No: of bags with buttons but no zips = 46

No: of bags that have both buttons and zipz = 110-(46+20+39) = 5

No: of bags with buttons = 46+ 5 = 51

Total no: of bags = 110

= 51/110
