Data Sufficiency — Practice

Question 1

What is the value of x?
Statement I: x − 3 = 10
Statement II: x is greater than 5

Accepted Answer

A

Question 2

Is n an odd number?
Statement I: n is divisible by 2
Statement II: n + 1 is an even number
(a) Statement I alone is sufficient
(b) Statement II alone is sufficient
(c) Both together are needed
(d) Either statement alone is sufficient

Accepted Answer

Statement I alone: if n is divisible by 2, n is even, so the definite answer to 'is n odd' is NO — this is a definite answer, so Statement I alone is sufficient (a 'no' is still a determinate answer).

Statement II alone: if n+1 is even, then n must be odd (since even−1=odd) — this gives a definite answer of YES, so Statement II alone is also sufficient. Since both work independently, the answer is (d).
