EDPT Sufficiency Analysis 3

Question 1

Is triangle PQR a right triangle? (1) PQ = QR. (2) PQ² + QR² = PR².

Accepted Answer

Statement 2 alone is sufficient

Answer

Statement 2 satisfies the Pythagorean theorem, confirming a right angle at Q; statement 1 only tells us it is isosceles.

Question 2

A computer program runs in T seconds. Is T < 5? (1) T is greater than 3. (2) T is less than 4.

Accepted Answer

Statement 2 alone is sufficient

Answer

If T < 4, then T is definitely less than 5; statement 1 alone cannot confirm T < 5.

Question 3

What is the area of circle C? (1) The diameter of C is 10. (2) The circumference of C is 10π.

Accepted Answer

Either statement alone is sufficient

Answer

Both the diameter and circumference independently determine the radius, so either alone gives the area.

Question 4

In a class of students, what percentage passed the exam? (1) 18 students passed. (2) 6 students failed.

Accepted Answer

Both statements together are sufficient, but neither alone is sufficient

Answer

Knowing both the number who passed (18) and failed (6) gives total = 24 and percentage = 75%.

Question 5

Is the product of integers m and n negative? (1) m is negative. (2) n is negative.

Accepted Answer

Neither statement alone nor both together are sufficient

Answer

If both m and n are negative, their product is positive, not negative; both statements together are not sufficient.
