In a certain warehouse, 60 % of the packages weigh less than 75 lbs, and a total of 48 packages weigh less than 25 lbs. If 80% of the packages weigh at least 25 pounds, howmany packages weigh at least 25 lbs but less than 75 lbs.

a)8

b)64

c)96

d)102

e)144

no typo this time

less than 75 lbs = 60%

at least 25 lbs = 80%

25 lbs or less than 25 lbs = 20% which equivalant = 48 packages

so 100% = 240

at least 25 lbs but less than 75 lbs = 40%

no of packages that weigh at least 25 lbs but less than 75 lbs = 40% of 240 = 96.
