Is the total profit from the sales of 3 products greater than $6?
1) The least profit from the sales of the 3 products is at least $2.1
2) The 2nd largest profit from the sales of the 3 products is at least $3.1.
In the current format the answer should be B and NOT A.
Note statement 1 : The least profit from the sales of the 3 products is at least $2.1
it DOES NOT say: The least profit from the sales of any ONE product is at least $2.1and all products were sold at a profit.(Ver.2)
IF the statement were as given in Ver.2 then it could have been sufficient.
The least profit from the sales of the 3 products is at least $2.1 , that means we are taking the profit of 3 products together. So together the profit from the 3 products could be $4 or $5 and answer would be no or the profit could be $6.1 or $10 and answer would be yes. Hence statement one is insufficient IMO.
Statement 2 : The 2nd largest profit from the sales of the 3 products is at least $3.1 , so the largest profit will be more than 3.1 hence total profit from these 2 products we will more than $6.2 . Hence B is sufficient .
