Each baby born at a certain hospital last week was either a single birth or one of a pair twins. If x is the number of babies born at the hospital last week, is x odd?
i) 33 single births
ii) 3 pairs of twins born
At present I do not have OA. However, this question was one among others I answered wrong at a previous mock test at my Gmat school
My line of reasoning was the below:
S - > single births
T - > twin births
X - > Total babies
S + 2T = X
i) 33 + 2T = X, which can be translated odd + even = odd, so i is SUFFICIENT
ii) S + 2*3 = X, NOT SUFFICIENT
so answer must be A, correct?
