Find the number of females in an office.
I. The ratio of number of males to females is 5: 4.
II. The number of males is 25% more than the number of females.
Let the number of males = x and number of females = y. From I, (x/y) = (5/4) Therefore, x = 1.25y From II, x = y +25% of y = 1.25y Since both the statements give the same equation, statement I and II both are not sufficient to answer the question.
