Delhi Police Constable | Computer Based Examination

Delhi Police Constable: full-length mock 2 (100 questions)

A second full-length Delhi Police Constable mock modelled on the Computer Based Examination: 100 original questions across General Knowledge and Current Affairs, Reasoning, Numerical Ability and Computer Fundamentals, weighted towards moderate and hard, each with a worked solution.

Before you start

100 questions in 90 minutes on a single clock — a full-length paper modelled on the Computer Based Examination.
Each question carries one mark; one fourth of a mark is deducted for a wrong answer, and unanswered questions carry no penalty.
The difficulty is deliberately weighted towards moderate and hard (about 76 of 100) so the set stays useful on repeat attempts. Every question is original with a worked solution shown after you submit.

Reasoning Ability · solved example

7 people — P, Q, R, S, T, U, V — sit in a row facing north. 4 people sit between P and Q. U sits 7th from the right end. S sits 3rd from the left end. R sits immediately to the right of T. 4 people sit between U and V. 3 people sit between S and Q.

Who sits 1st from the left end?

P
UCorrect
T
R
W

Solution

Working through the clues fixes the order as U, P, S, T, R, V, Q from the left, so the 1st person is U.

Quantitative Aptitude · solved example

In each, solve for x and y and give the relation: I. x² + 4x − 45 = 0 II. y² + 10y − 11 = 0

x > y
x < y
x ≥ y
x ≤ y
no fixed relationCorrect

Solution

The roots are x = 5, -9 and y = -11, 1. Comparing every x with every y gives "no fixed relation".
