    Show answer and solution

    Answer: (A) Carbon monoxide
    कार्बन मोनोऑक्साइड

    Carbon Monoxide (CO) has a much higher affinity for hemoglobin than oxygen, forming carboxyhemoglobin which prevents oxygen transport.
    कार्बन मोनोऑक्साइड (CO) की हीमोग्लोबिन के लिए ऑक्सीजन की तुलना में बहुत अधिक आकर्षण होती है, जिससे कार्बोक्सीहीमोग्लोबिन बनता है जो ऑक्सीजन परिवहन को रोकता है।
  3. Arithmetical & Numerical Ability

    25 परिणामों का औसत 18 है। उनमें से पहले बारह का औसत 14 है और अंतिम बारह का औसत 17 है। तेरहवां परिणाम है:
    1. 72
    2. 75
    3. 78
    4. 81
    Show answer and solution

    Answer: (C) 78

    Sum of 25 results = 25 * 18 = 450.
    Sum of first 12 = 12 * 14 = 168.
    Sum of last 12 = 12 * 17 = 204.
    13th result = 450 - (168 + 204) = 450 - 372 = 78.
    13वां परिणाम = 450 - 372 = 78.

Our test applies the same 1 and 0.25, so the score you see is comparable with the real one. At 0.25 per mistake, a blind guess across four options is worth taking only when you can rule out at least one.

The other 2019 papers

Frequently asked questions

How many questions from the 2019 Shift 1 paper are on this page?

This test has 180 of the 200 questions from the 16 July 2019 Shift 1 paper. These sections are still incomplete: General English (20 of 40). We publish the real count rather than padding the paper with questions DSSSB did not ask.

Is the answer key the official one?

Yes. Every correct option is the one DSSSB ticked in its own answer-key PDF for this shift. The worked solutions underneath are written for this site and are not part of the official key.

Do I need to log in to take the test?

No. The test starts without an account. Creating one only saves your result so you can compare attempts later.

What is the marking scheme?

The same as the real paper: 1 mark for a correct answer, 0.25 deducted for a wrong one, nothing for a question you leave blank. The timer is set to the official 120 minutes.

Why does my option number differ from the PDF?

DSSSB switched on option shuffling for this exam, so the order on a candidate's screen was not the order in the PDF. Match your answer by the option text, not its number.
