Re: Two teams A and B comprising of 3 members each take part [#permalink]

I tried the problem in the following way:
Let team A consists of members as x,y,z
Let team B consists of members as p,q,r
statement 1- The total number of correct solutions by both the teams together is 25, as the total is 25 and the number of questions are 6, the worst case situation is that each member of team b solve all questions correctly, then team b points are 3 * 6 (number of questions), team a should have 7 points. taking possibilities of this situation
if x - 6, y- 1, and z -0
x- 5, y - 2, z -0
x - 4, y - 3, z- 0
x- 3 , y, -3, z -1 --> note that the numbers can be interchanged between x, y, and z and in either way, any member of team a solves 3 questions, therefor sufficient info.
Statement 2 -> it is just the second part of analysis of statement 1, therefore sufficient.
