Ratio And Propotion In Aptitude For Competitive Exams

Ratio And Propotion Topic Is Very Important For Bank Exams, CAT, SSC , GATE, Campus And Other Competition Government Exams.

Ratio

1.The Ratio Of a and b Is Called Fraction a/b And We Can Write It As a:b.
2.In (a:b) a Is Called Antecedent And b Is Called Consequent.
3.The Multiplication, addition And Division Does not Affect The Ratio.
Example: a/b = a*3/b*3 = (a/3)/(b/3) = a+3/b+3
4.Ratio Is unitless Quantity.
5.We Can Divide The Ration In Following Types:
A.Duplicate Ratio: a^2:b^2 Is The Duplicate Ratio Of a:b.
B.Sub-Duplicate Ratio: (a^1/2):(b^1/2) Is Sub Duplicate Ratio Of a:b.
C.Sub-Triplicate Ratio: (a^1/3):(b^1/3) Is Subtriplicate Ratio Of a:b.
D.Compound Ratio: ab:cd Is The Compound ratio Of (a/b) And (c:d).
E.Inverse Ratio: 1/a:1/b Is The Inverse Ratio Of a:b.
F.Componendo And Dividendo: If We take a/b And c/d Then According To Componendo and Dividendo Rule:
a/b = c/d = a+b/a-b = c+d/c-d

Propotion

1.The Equality Of Two Ratio Is called Propotion.
Example: If We take a/b = c:d, Then We can Also Write Is a:b::c:d
a and d Called Extremes And b and c Called means Terms
There Is Relation Between Mean Terms And Extremes, That is:
Product Of Extreme = Product Of Means terms
a*d = b*c
2.Third Propotion: If We Take a/b=b/c Then b Is Called Third Propotion. and b^2 = a*c
And These a, b And c Are In Continued Propotion.
3.Fourth Propotion: If We Take a, b, c, d Then a:b = c:d Then There Is Relation Like ad=bc And d is called fourth propotion of a,b and c.

Some useful Terms And Relations:

If We take a:b/c:d Then Following Relation Would Hold
A.Intervendo = b:a=d:c
B.Alternendo = a:c=b:d
C.Componendo = (a+b):b = (c+d):d
D.Dividendo = (a-b):b = (c-d):d

Profit And Loss Concept In Aptitude For Competitive Exams

Profit And Loss Concept And Problems For Competitive Exams Like CAT, SSC, IBPS Bank PO, IAS, Gate, Company Campus Exams And Other Government Exams.

First Of All We Take Basic Terminologies For The Profit And Loss Topic:
1.Selling Price(SP): The Price On Which Object Would Be Sold, Is Called Selling Price.We Will Represent Selling Price As SP.
2.Cost Price(CP): The Price On Which, Object Is Purchased, Would Be Called Cost Price.We Will Represent Cost Price As CP.
3.Profit(P): When Any Person Sold A Particular object Greater Amout Than He Purchased Then He Got Profit(P).Profit Is Denoted As P.
4.Loss(L): when Any Person Sold Object Smaller Price Than He Purchased Then That Person Got Loss Definitely.
5.Marked Price(MP): The Price Mentioned On The Object Is Called Marked Price. List Price Is Treated As Its Synonym.
6.Discount: It Is The Reduction On Marked Price Provided By The Seller To The Customer.It Is Write As d.
…………………………………………………………………………………………………………………………………………………………………………………….
Important Formulas On Profit And Loss:

• Profit(P) = Selling Price – Cost Price = SP – CP
• Profit Percentage = [(Profit)/Cost Price]*100
• Selling Price(SP) In Profit = [(100+Profit Percent)/100]*Cost Price(CP)
• Loss(L) = Cost Price(CP) – Selling Price(SP) = CP -SP
• Loss Percentage = [(Loss)/(Cost Price)]*100
• Selling Price(SP) In Loss = [(100-Loss Percent)/100]*Cost Price(CP)
• Discount(d) Percentage = d% = (Discount/ Marker Price)*100
• Selling Price(SP) = [(100-d%)]/100*MP
