Sample questions with worked solutions

A few questions from this test, with the answer key and the method behind it. The full set of 28 runs under a timer, and every solution is on the analysis screen once you submit.

General Awareness · solved example

The Durand Line forms the border between Pakistan and:

India
AfghanistanCorrect
China
Iran

Solution

The Durand Line is the Pakistan–Afghanistan boundary.

General Intelligence & Reasoning · solved example

Find the next term in the series: K, M, O, Q, ?

M
W
SCorrect
P
V

Solution

Each letter advances by 2 places in the alphabet, so the term after Q is S.

Mathematics · solved example

In each, solve for x and y and give the relation: I. x² − 10x + 21 = 0 II. y² + 2y = 0

x > yCorrect
x < y
x ≥ y
x ≤ y
no fixed relation

Solution

The roots are x = 3, 7 and y = -2, 0. Comparing every x with every y gives "x > y".

General Science · solved example

The hardest known natural substance is:

Iron
Quartz
DiamondCorrect
Graphite

Solution

Diamond, a crystalline form of carbon, is the hardest natural material known.
