An engineering college invited 600 students for the counselling round. Two-thirds of the students were rejected right away for insufficient documents and the rest were given a choice of atleast one branch out of A, B and C. For every two students who were given the choice of only branch A, one more was given the choice of only branch B. For every five students who were given the choice of only branch C, three less were given the choice of only branch B. The number of students who got the choice of both B and C was 60 and the ratio of students who got the choice of both A and C to those who got the choice of both A and B was 5 : 7.

1. The number of students who got exactly two choices was 60 and the ratio of the number of students who got the choice of both C and B but not A to the number of students who got the choice of both A and C but not B is 2 : 1. How many students got a choice of all three branches

6. CAT - Sets & Venn Diagram

On Republic day 550 students of model high school were present for a special assembly. Once the assembly was over, principal asked the students to pick chocolates of their choice from 3 boxes kept at corner of the ground. Boxes 1, 2 and 3 contained chocolates Milkybar, DAIRY MILK and 5 STAR respectively. Owing to lack of teachers, students went havoc and picked as many chocolates as they could.

    2. 44 students picked all three types. No one picked more than one from any box. 45 students were disappointed to see all boxes empty

1. If the number of students who picked both DAIRY MILK and Milkybar but not 5 STAR is 79, then how many students picked only 5 STAR?

2. If the number of students who picked only Milkybar is 87, how many students picked both DAIRY MILK and 5 STAR? (Use data from previous question if necessary.)

3. Number of students who picked only 5 STAR is greater than the number of students who picked only Milkybar. Also, the number of students who picked only Milkybar is greater than number of students who picked only DIARY MILK. What is the maximum number of students who picked both 5 STAR and Milkybar but not DAIRY MILK?
