Question

A company makes 140 bags.
39 of the bags have buttons but no zips.
21 of the bags have zips but no buttons.
23 of the bags have neither zips nor buttons.
How many bags have zips on them?

Answer 1

Answer:

78 bags have zips in them

Step-by-step explanation:

bags with zip = bag with button and zip+ bag with no button but only zip

i.e.

total bags-(bags with neither of two + bags with only buttons)

140-(39+23)

140-62

78

hence , ans=78
