Two teams A and B comprising of 3 members each take part in a Math competition. The test consists of 6 problems and if any member of a team solves 3 problems correctly, then the member wins a gold medal. Did any member of Team A win a gold medal?

1. The total number of correct solutions by both the teams together is 25

2. The number of correct solutions by members of Team A is 7 more than that of Team B

1. The total number of correct solutions by both the teams together is 25The max correct answers of the 3 members answering 6 questions correctly = 6 * 3 =18

Then, we are left with 7 questions answered correctly by team A......Therefore, we are certain that there is a a member answered 3 questions correctly.

So, at lease one member answered 3 questions correctly.

If we decrease correct questions from team B so it means that it adds to team A to make up the 25 correct questions.

Sufficient

2. The number of correct solutions by members of Team A is 7 more than that of Team Bcorrect questions by Team A = 7 + correct questions by Team B

if B does not answer any question correctly....at we have 7 questions answered correctly by team A, making one member answered 3 questions correclty. It is same as statement 1.

Sufficient

Answer: D
