RRB ALP | Computer Based Test 1

RRB ALP: full-length mock (75 questions)

A full-length RRB ALP mock modelled on the Computer Based Test 1: 75 original questions across Mathematics, Mental Ability and Reasoning, General Science and General Awareness on Current Affairs, weighted towards moderate and hard, each with a worked solution.

Before you start

  • 75 questions in 60 minutes on a single clock — a full-length paper modelled on the Computer Based Test 1.
  • Each question carries one mark; one third 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 52 of 75) so the set stays useful on repeat attempts. Every question is original with a worked solution shown after you submit.

Sample questions with worked solutions

A few questions from this test, with the answer key and the method behind it. The full set of 75 runs under a timer, and every solution is on the analysis screen once you submit.

Mathematics · solved example

In each, solve for x and y and give the relation: I. x² − 10x + 16 = 0 II. y² − 3y − 4 = 0

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

Solution

The roots are x = 8, 2 and y = 4, -1. Comparing every x with every y gives "no fixed relation".

General Intelligence & Reasoning · solved example

Four of the following five are alike in a certain way and form a group. Which is the one that does not belong?

  • 19
  • 5
  • 43
  • 17
  • 48Correct

Solution

Every number except 48 is a prime number, so 48 is the odd one out.

General Science · solved example

What is the SI unit of pressure?

  • Joule
  • PascalCorrect
  • Bar
  • Newton

Solution

The pascal is the SI unit of pressure.

Current Affairs · solved example

Which Article of the Constitution guarantees equality before the law?

  • Article 14Correct
  • Article 19
  • Article 21
  • Article 32

Solution

Article 14 guarantees equality before the law and equal protection of the laws.

Mathematics · solved example

Find the volume of a cylinder of radius 21 cm and height 15 cm (take π = 22/7).

  • 20790Correct
  • 25165
  • 23290
  • 18290
  • 16415

Solution

Volume = πr²h = 22/7 × 21² × 15 = 20790 cubic cm.

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.
