Sample Mathematics questions with solutions

Written to the RRB Section Controller pattern, with the answer key and the method behind it — a look at how the section is actually set before you drill the full topic sets.

Simple interest · solved example

Find the simple interest on Rs 2000 at 5% per annum for 3 years.

  • 240
  • 360
  • 330
  • 300Correct
  • 270

Solution

SI = P×R×T/100 = 2000×5×3/100 = 300.

Pipes and cisterns · solved example

One pipe fills a tank in 6 hours while another empties it in 9 hours. If both are opened together, in how many hours will the tank be filled?

  • 20
  • 12
  • 18Correct
  • 15

Solution

Net filling rate is 1/6 − 1/9 = 1/18 of the tank per hour, so it fills in 18 hours.

Time and work · solved example

A can do a piece of work in 12 days and B in 18 days. Working together, in how many days will they finish it?

  • 7.5
  • 7.2Correct
  • 7
  • 6.8

Solution

Together they do 1/12 + 1/18 = 5/36 of the work a day, so the whole work takes 36/5 = 7.2 days.

Approximation · solved example

Find the approximate value: 24.9% of 360.

  • 57
  • 156
  • 123
  • 24
  • 90Correct

Solution

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