Answer / hem sagar
we need remaining 25 buyers..so we cant limit the total
no.of people.if there are total X no.of people out of which
500 random samples were taken and 75 were pulled out so the
rest of 25 are in X-500 people(u can call these as left over
people) X might be 525 or 5000..we cant tell but even though
if x is 126 and the 126th person is juice buyer and u have
taken only 125 samples as answered by earlier its wrong..
**so answer is for remaining 25 all the remaining people**

Answer / shashank
Since we have to find the REMAINING 25 people who buy juice, we can consider that we have to find all the 100 people. Out of these 100 people, we already have it in the question that out of 500 people 75 people buy juice.
This was of the probability 3/4.
Now to find the remaining people, whose probability is 1/4. Simply, 1/4*500 = 125.
Now, since the remaining 25 people were not found in the initial 500 and assumed to be found in the 125 lot,
we can add 500 to 125.
Thus, we get 625.

Answer / n
PEOPLE:100/4=25
JUICES:500/4=125
FOR 75 PEOPLE:125*3=375 (i.e)PEOPLE 25*3=75
Then JUICE 125*3=375
Therefore for remaining 25 buyers=500-375
=125
ANSWER:125

Substitute digits for the letters to make the following addition problem true. W H O S E T E E T H A R E + A S ------------------- S W O R D S Note that the leftmost letter can't be zero in any word. Also, there must be a one-to-one mapping between digits and letters. e.g. if you substitute 3 for the letter H, no other letter can be 3 and all other H in the puzzle must be 3.
