SOLUTION:
Using Statement (1)
Of those who received a P, 40% were females.
=>0.4p students are females. However, since we know neither the values of P, F & I nor the percentage of students who received an F or I,
Statement (1) alone is INSUFFICIENT to answer the question.
Using Statement (2)
Of those who received either an F or I, 80% were males.
=>20% of the students who received either an F or I were females.
=> 0.2(F+I) students are females. However, since we know neither the values of P, F,
& I, nor the percentage of students who received a P,
Statement (2) alone INSUFFICIENT to answer the question.
Using both (1) and (2)
From the two statements, we can say that the percentage of students in the class who were females is:
(0.4p + 0.2(F + I))/(P+ F + I) * 100
However, since we don’t know the values of P, F, and I, we can’t determine the numerical value of the expression above.
Statements (1) and (2) together are INSUFFICIENT.
Thus OPTION E
