Jeff observed that 60% of people at the mall shop for cloths on a particular day. if 25000 people did not shop for cloths that day the number of people who shopped for cloths that day?

If 60% of people shopped for clothes, then 40% did not shop for clothes.

and 25,000 did not shop for clothes ...

so 40% of the total people is 25,000

0.40x = 25,000

x = 25,000 / 0.40

x = 62,500 total people

so if the total people is 62,500 and 25,000 of them did not shop for clothes, then (62,500 - 25,000) = 37,500 < = = shopped for clothes
