Question

A is heavier than C, B is lighter than D, Fis heavier than E,D is heavier than C and F.Who is lightest?​

Answer 1

B is the lightest.

A > C,

D > B,

F > E,

D > C, and

D > F.

A > D > C > F > E > B.

Answer 2

E is the lightest among all the 6 students.

1. The given data is,

• A is heavier than C, Hence the order is A > C.
• D is heavier than B, Hence the order is D > B.
• F is heavier than E, Hence the order is F > E.
• D is heavier than C, Hence the order is D > C.
• C is heavier than F, Hence the order is C > F.

2. Since D is heavier than C and C is heavier than F, the order for the three students will be D > C > F. As F is heavier than E the order for the four students will be D > C > F > E. As D is greater than B, the value of B can also be less than the value of E, Hence the other possible order is D > C > F > E > B.

3. The given data is insufficient to find the heaviest student among the given 6 students, but using the above comparison of the 4 students, E is the lightest. The weights of students A and B lie somewhere in between D to E, but the weights of A and B are not less than the weight of E.

Therefore, student E (OR) student B can be the lightest among all the other students.
