Formula
Dividend = Divisor × Quotient + Remainder
Whole numbers, factors, remainders and divisibility. LCM/HCF is the neighbouring chapter.
What you should learn here
Remainder questions in SSC often hide the form N = LCM×k + R. Write that line first.
Worked example
Question. Smallest number that leaves remainder 1 when divided by 2, 3 and 5?
Solution. LCM(2,3,5)+1 = 31.
Common mistake. Using HCF where the question asks for a common multiple (LCM).
When to use the shortcut. Divisibility rules (2,3,4,5,8,9,11) should be automatic before you open a calculator habit.

FAQs
Are these previous-year SSC questions?
No year or shift is claimed on these pages. Each maths section has 150 original practice MCQs. When a verified source database exists, a question will show exam + year; until then it is practice.
Where are Class 10 board formulas?
The CBSE formula sheet at /cbse/class-10/mathematics/formulas/ stays the canonical board list. This maths hub links to it instead of copying every line.
Do you publish tricks that are only sometimes true?
Every shortcut page states when the trick must not be used. A speed trick that fails on close options is not published as if it were a theorem.
