#DILR-2
A party was organized in a college in which three types of cold drinks were served. The served cold drinks were Pepsi, Coke and Sprite. There were 500 students in the college but 10% students did not drink any of the three cold drinks. A total of 750 bottles of cold drinks were served at the party.
It is known that cold drinks were served in bottles only and no student drank more than one bottle of the same type of cold drink. The additional information is given below:
(i) The number of students who drank Pepsi and Coke both was equal to the number of students who drank Pepsi and Sprite both.
(ii) The number of students who drank Coke and Sprite but not Pepsi was twice the number of students who drank all the three cold drinks.
(iii) The number of students who drank Pepsi and Sprite but not Coke was more than 50.
(iv) The number of students who drank all the three cold drinks was at least 1.
#Q1 If the difference between the numbers of students who drank Pepsi and Sprite but not Coke and that of those who drank all the three cold drinks was minimum but not zero, then what was the number of students who drank at least 2 types of cold-drinks?
#Q2.The minimum number of students who drank only one bottle cold-drink?
#Q3. Additional information should not be considered for this question. If at least 315 students drank Pepsi, at least 360 students drank Coke and at least 405 students drank Sprite, then find the minimum possible number of students who drank all the three cold-drinks.
#Q4 Additional information should not be considered for this question. Had three more cold drinks – Limca, Dew and Appy – been served at the party and exactly 450 students liked Pepsi, 400 liked Coke, 350 liked Sprite, 300 liked Limca, 200 liked Dew and 50 liked Appy, then what would have been the maximum number of students who liked exactly four cold-drinks?
(Assume the number of the bottle served at the party could be more than 750.)
SOLUTION-
10% are not drinking any of the drink,
so null = 10/100 *500=50
So people drinking atleast 1 drink = 450
ex1-exactly 1 drink
ex2-exactly 2 drink
ex3-exactly 3 drink
ex4-exactly 4 drink
ex5-exactly 5 drink
ex6-exactly 6 drink
