Sample questions with worked solutions

A few questions from this test, with the answer key and the method behind it. The full set of 30 runs under a timer, and every solution is on the analysis screen once you submit.

Quantitative Aptitude · solved example

In an election between two candidates, the winner secured 58% of the valid votes and won by 4800 votes. How many valid votes were polled?

  • 24000
  • 27000
  • 30000Correct
  • 32000
  • 36000

Solution

The winner had 58% and the loser 42%, a gap of 16% of the valid votes. That 16% equals the winning margin of 4800, so the total is 4800 / 0.16 = 30000. Turn the margin into a percentage of the whole before dividing.

General Science · solved example

English Language · solved example

Find the part that contains an error. If there is no error, mark (e). (a) He is one of the / (b) most honest officer / (c) that this branch / (d) has ever employed.

  • (a)
  • (b)Correct
  • (c)

Solution

'One of the' is followed by a plural noun, so part (b) should be 'most honest officers'. The superlative describes a group from which one is drawn.

Reasoning Ability · solved example

Statements: E < D ≤ B = F Conclusions: I. B ≥ D II. B > F Which conclusion(s) definitely follow?

  • Only I followsCorrect
  • Only II follows
  • Both I and II follow

Reading the chain, conclusion I is true and conclusion II is not necessarily true. Hence: only i follows.

Because a blank carries no penalty, guessing only pays when you can eliminate at least two options. The analysis screen after the test shows you exactly where guessing cost you marks.
