Why Pattern Repetition Matters in DSSSB Arithmetic
Analysis of DSSSB question papers from 2014 through 2025 demonstrates that the Delhi Subordinate Services Selection Board frequently recycles mathematical archetypes with numerical variations. The **Price-Consumption-Expenditure** and **Venn Diagram Pass/Fail** models have appeared in almost every exam cycle with recurrence frequencies ranging between 3 to 7 times across TGT, PGT, and PRT shifts.
High-Frequency Fractional Conversions in DSSSB Exams
| Fraction | Percentage | Frequency in PYQs |

Frequently Asked Questions (DSSSB Maths Percentage)
1. How many questions are asked from the Percentage topic in DSSSB TGT Computer Science?
Direct percentage questions account for 2 to 3 marks out of 20 in Section A (Arithmetic Ability). However, topics like Profit & Loss, Simple & Compound Interest, Discount, and DI rely directly on percentage principles, yielding a total combined weightage of 7–9 marks.
2. Is there negative marking in DSSSB TGT and PGT exams?
Yes, DSSSB conducts CBT exams with a negative marking deduction of 0.25 marks for each incorrect response, while every correct answer earns 1 mark.
3. What does the "Frequency Count" signify in this practice test?
The frequency count indicates how many times the underlying mathematical pattern (e.g., expenditure neutralizer, net area shift, or two-set Venn pass/fail) has surfaced across different shifts of DSSSB exams between 2014 and 2025.
4. Why is this online mock test timed for 20 minutes for 150 questions?
This speed drill is designed to train rapid pattern recognition (under 8–10 seconds per question). In the actual DSSSB CBT exam, answering arithmetic questions swiftly reserves crucial time for technical Section B questions (Computer Science / Subject Knowledge).
5. Can these PYQs help for other exams like DASS Grade IV, PRT, or DSSSB PGT?
Yes. The syllabus, test layout, and difficulty level of Section A are identical across all DSSSB Group B and Group C teaching and non-teaching posts.
