RRB Technician | Computer Based Test for Technician Grade III

RRB Technician: full-length mock (100 questions)

A full-length RRB Technician mock modelled on the Computer Based Test for Technician Grade III: 100 original questions across General Science, Mathematics, General Intelligence and Reasoning and General Awareness and Current Affairs, 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 Test for Technician Grade III.
  • 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 64 of 100) so the set stays useful on repeat attempts. Every question is original with a worked solution shown after you submit.

  • 57
  • 156
  • 123
  • 24
  • 90Correct

Solution

Round to 25% of 360 ≈ 90, which is the closest option.

General Intelligence & Reasoning · solved example

7 people — P, Q, R, S, T, U, V — sit in a row facing north. 4 people sit between T and Q. T sits 7th from the right end. P sits immediately to the right of V. 5 people sit between T and U. V sits 6th from the right end. S sits 4th from the left end.

How many people sit between R and U?

  • 7
  • 2
  • 3
  • 4
  • 1Correct

Solution

The order is T, V, P, S, R, Q, U from the left; between R and U there are 1 people.
