(II) The digit at unit place is 75% o If the data in statement (II) alone is sufficient to answer the question, while that in statement (I) alone is not sufficient. If the data in statement (I) alone is sufficient to answer the question while that in statement (II) alone is not sufficient. If the data even in both statements (I) and (II) together is not sufficient to answer the question. If the data either in statement (I) alone or in statement (II) alone is sufficient to answer the question. If the data in statement (II) alone is sufficient to answer the question, while that in statement (I) alone is not sufficient. If the data in statement (I) alone is sufficient to answer the question while that in statement (II) alone is not sufficient. If the data even in both statements (I) and (II) together is not sufficient to answer the question. If the data either in statement (I) alone or in statement (II) alone is sufficient to answer the question. ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Let the number be 10x + y∴ 3x = 4y ......(1)From (I),x + y = 14 .....(2)Solving equations (1) and (2),x = 8, y = 6∴ Number = 86 From (II)y = 75/100 x x ∴ 3x = 4y.Which is the same as eqn (1)
