Explanatory Answer
Method of solving this CAT Quantitative Ability Question from Permutation, Combination and Probability question
(d) Given that A > B > G > F. Satisfying this condition, ifF = 2, then, G = 3, B = 4, A = 5.
But this violates the condition that adults per familyshould be atmost 2.
Hence, we take the next option : F= 3, then G = 4, B = 5, A = 6.
Here all conditions are satisfied. Hence, the answer is(d).
