Product of means = Product of extremes bxc=axd a:b::c:d a:b=c:d a/b=c/d Properties of Ratio & Proportion:- ------------------------------------------ (I) Invertendo:- If a/b=c/d then b/a=d/c. (II) Alternendo:- If a/b=c/d then a/c=b/d. (III) Componendo:- If a/b=c/d then (a+b)/b=(c+d)/d. (IV) Dividendo:- If a/b=c/d then (a-b)/b=(c-d)/d. (V) Componendo & Dividendo If a/b=c/d then (a+b)/(a-b)=(c+d)/(c-d). (VI) Fourth Proportion:- If a/b=c/d then d is called the 4th proportion. VII) Third Proportion:- If a/b=b/c then c is called the 3rd proportion. VIII) Mean Proportion:- The mean proportional b/w a & b is √ab. (IX) Duplicate Ratio:- The duplicate ratio of a:b is a^2:b^2. (X) Sub-duplicate Ratio:- The Sub-duplicate ratio of a:b is √a:√b. (XI) Triplicate Ratio:- The triplicate ratio of a:b is a^3:b^3. XII) Sub-triplicate Ratio:- The sub-triplicate ratio of a:b is a^1/3:b^1/3. XIII) Compounded Ratio:- The compounded ratio of the ratios (a:b),(c:d) is ac:bd. -------------------------------------------------------- Number System:-    • Number System   Sumplification:-    • SIMPLIFICATION   Problems on Ages:-    • Problems on Ages   HCF & LCM:-    • HCF and LCM   Average:-    • Average   Volume & Surface Area:-    • Volume and Surface Area   Area(2D):-    • Area (2D)   Percentage:-    • Percentage   SI :    • Simple Interest   CI :    • Compound Interest   Profit & Loss:-    • Profit and Loss   Probability:-    • Probability   Problems on Trains:-    • Problems on Trains   Permutation & Combination:-    • Permutations & Combinations   Time & Distances:-    • Time and Distance   Time & Work:-    • Time and Work   Algebra:-    • Algebra   Trigonometry:-    • Trigonometry   Discount:-    • Плейлист   Boats & Streams:-    • Плейлист   Geometry:-    • Плейлист   Pipe & Cistern:-    • Плейлист   Alligation or Mixture:-    • Плейлист   Statistics:-    • Плейлист   Coordinate:-    • Плейлист   Set Theory:-    • Плейлист   Clock & Race:-    • Плейлист   Calendar:-    • Плейлист   DI:   • Плейлист   DS:   • Плейлист   ------------------------------------------------------------------------------- #Ratio&ProportionGCC #Quant #RatioProportion #RatioAndProportion #IBPS #NTPC #Aptitude #QuantitativeAptitude #SSC ------------------------------------------------------------------------------- Quantitative Aptitude:- RATIO AND PROPORTION Qu(71):- What is the ratio in ₹2.80 and 40 paise?
