Quantitative Aptitude Questions for SSC and DSSSB

Count read live from the question bank. Questions withdrawn for being wrong or unanswerable leave this page automatically.

In short: 484 quantitative aptitude questions with the answer and a worked solution under each one. A test serves 25 at a time, marked +1 and −0.25 like the real paper, and starts without a login.

What this section tests

Quantitative aptitude rewards a short list of methods applied quickly. Percentage, ratio and time-and-work questions reward a method you have drilled; trigonometry rewards knowing the identities cold. A test here is 25 questions, the same length as the SSC CGL quant section, so it works as a section rehearsal.

What is in this bank, by topic

The largest groups are Arithmetic (144, 57%), Trigonometry (55, 22%), Geometry & Mensuration (32, 13%). Data interpretation, tables and charts, is almost absent here: 1 question. If your paper has a data-interpretation set, this bank is not where to practise it.

Grouped by keyword on 16.09.2026, one topic per question. A question on the boundary of two topics can sit in either group, so read this as a guide. The live total above can be higher, because questions are added after this count.

Where these questions come from

A question from a DSSSB paper carries DSSSB's own answer; a practice-pool question carries ours.

Solved quantitative aptitude questions

A few from the bank, with the answer and the working behind a toggle. Try them before you open the answer.

  1. A student scored 180 marks out of 300. What is his percentage score?
    1. 50%
    2. 55%
    3. 60%
    4. 65%
    Show answer and solution

    Answer: (C) 60%

    Percentage = (Scored Marks ÷ Total Marks) × 100 = (180 ÷ 300) × 100 = 60%.
  2. The value of which of the following is different from the other options?
    1. sec 60°
    2. sin 90°
    3. cos 0°
    4. tan 45°
    Show answer and solution

    Answer: (A) sec 60°

    sec60° = 2, others = 1 so sec60° is different.
  3. The value of cosec 30° − cos 60° is:
    1. 2√2/√2
    2. 3/2
    3. 1/2
    4. 1
    Show answer and solution

    Answer: (B) 3/2

    cosec30°=2, cos60°=1/2 ⇒ 2−1/2 = 3/2 (Check carefully). Correct is 3/2.
  4. If cos θ = √3/2 , then tan2θ cos2 θ = ?
    1. √3
    2. 1/4
    3. 1/√3
    4. 1/2
    Show answer and solution

    Answer: (B) 1/4

    cosθ=√3/2 ⇒ sinθ=1/2 ⇒ tanθ=1/√3 ⇒ tan²θ cos²θ=(1/3)*(3/4)=1/4 ??? Check ⇒ Actually question intends 2θ. Using double angle gives √3.

Frequently asked questions

What topics do these quantitative aptitude questions cover?

Grouped by keyword on 16.09.2026 across 254 questions: The largest groups are Arithmetic (144, 57%), Trigonometry (55, 22%), Geometry & Mensuration (32, 13%). A question on the boundary of two topics can sit in either group, so read the counts as a guide rather than an audit.

Is there data interpretation in this bank?

Almost none: 1 question is grouped as data interpretation, so it is not a topic to prepare with this bank.

How long should one maths question take?

DSSSB ASO Tier 1 gives 200 questions in 2 hours and SSC CGL Tier 1 gives 100 in 60 minutes. Both are 36 seconds a question on average. Maths is where that average bites hardest, because a worked calculation takes longer than reading a vocabulary question, so take the quick percentage and ratio questions first and come back for the long ones.

Do the solutions show the working?

314 of the 484 questions carry a written solution. After you submit, each one shows the correct option and the working behind it.

How is this section marked in the tests here?

1 mark for a correct answer and 0.25 deducted for a wrong one, matching the DSSSB paper these questions come from. A question you leave blank costs nothing, and no login is needed to start.
