Mixture and Alligation — formula, example and practice
Alligation cross for two-price mixes. Check whether the mean is weighted.
Content type: original worked example. Not labelled as a previous-year question.
Timed GK/quant mock Shortcuts CBSE Class 10 Maths 150 questions
Formula
Alligation: (dear − mean) : (mean − cheap) = cheap qty : dear qty (cross)
Mix two prices or two concentrations to hit a mean.
What you should learn here
Alcohol-water replacement problems are mixture plus the leftover-fraction (1 − removed/total)^n.
Worked example
Question. Mix rice at ₹ 20/kg and ₹ 30/kg to get ₹ 24/kg. Ratio?
Solution. (30−24) : (24−20) = 6 : 4 = 3 : 2 (cheap : dear).
Common mistake. Writing the ratio dear:cheap instead of cheap:dear — check which side of the cross you used.
When to use the shortcut. Alligation is only for two groups mixed into one mean. Three-item mixes need weighted equations.

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.
