 अनुपात समानुपात शार्ट ट्रिक्स Ratio and Proportion

In this article we are going to share some important and interesting short tricks of ratio and proportions questions in Hindi as well as English questions. With the help of this tricks students will learn how to solve ratio and proportions problems in very few minutes. It's very important for those candidates who are appearing in various competitive examination.
Ratio:-  
            The division of two numbers is known as Ratio. It is denoted by (:).
            Example: 5:7 or 5/7 , 2:3 or 2/3 etc.

Type and Ratio Short Trick 1:

If A : B = X : Y and B : C = P : Q ,then:-
  1. A : C = X x P : Y x Q
  2. A : B : C = (X : Y) x P :Y x Q = X x P : Y x P : Y x Q
                 or        A    :    B   :   C
                            X    :   Y
                                \      |      \  
                                      P     :    Q
                        ___________________
                         X x P : Y x P : Y x Q
   Example: If  A : B = 4 : 5 and B : C = 6 : 7 then, find value of A : C ?





Type and Ratio Short Trick of  2:

              If A : B = X : Y , B : C = P : Q and C : D = M : N then:-
  1. A : D = X x P x M : Y x Q x N
  2. A : B : C : D = (XP : YP : YQ) x M : Y x Q x N                                                                                       = XPM : YPM : YQM : YQN


Example:  If A : B = 3 : 4 , B : C = 8 : 9 and C : D = 12 : 13 then, find value of A : D ?






Important question of ratio and proportion asked in previous exam
Q1
Divide Rs. 672 in the ratio 5: 3. 
६७२ को : में विभाजित करो 
ANS:
Sum of ratio terms = (5 + 3) = 8.
First part = Rs. (672 x 5/8) = Rs. 420; 
Second part = Rs. (672 x 3/8) = Rs.   252.
Q2
Divide Rs. 1162 among A, B, C in the ratio 35: 28: 20.
११६२ को  A, B, C  में ३५: २८:२० में विभाजित करो. 
ANS:
Sum of ratio terms = (35 + 28 + 20) = 83.
A’s share = Rs. 1162 x35/83) = Rs. 490;
B’s share = Rs.  
1162x28/83) = Rs. 392
Q3
A bag contains 50 p, 25 p and 10 p   coins in the ratio 5: 9: 4, amounting to rs 206. Find the number of coins of each type.
एक बैग में ५० पैसे २५ पैसे एवं  १० पैसे के सिक्के :: में हेजो २०६ रुपए  हे. हर प्रकार के कितने सिक्के हे 
ANS:
Let the number of 50 p, 25 p and 10 p coins be 5x, 9x and 4x respectively.
5x 9x 4x
Then5x/2 + 9x/4 + 4x/10=206
50x + 45x + 8x = 4120 
= 103x = 4120 
x = 40.
Number of 50 p coins = (5 x 40) = 200;
Number of 25 p coins = (9 x 40) = 360;
Number of 10 p coins = (4 x 40) = 160
Q4
A mixture contains alcohol and water in the ratio 4: 3. 115 liters of water is added to the mixture, the ratio becomes 4: 5. Find the quantity of alcohol in the gives mixture.
 एक देब्बे मे अलकोहल एवं पनि का 4:3 का मिश्रण हे। यदि उस मिश्रण मे 115 लिटर पनि और मिला दिया जाए तो उसका अनुपात 4:5 हो जाएगा। अल्कोहल्क की मात्रआ ज्ञात करो।
ANS:
Let the quantity of alcohol and water be 4x liters and 3x liters respectively Then.
4x / (3x+5) = 4/5
= 20x = 4 (3x + 5) 
8x = 20 
x = 2.5.
=3x+5 5
Quantity of alcohol = (4 x 2.5) liters = 10 liters

Type and Ratio Short Trick 3:

  1. If  A : B : C : D = W : X : Y : Z and D : E = M : N  then
                                     and
     2. If  A : B : C : D = W : X : Y : Z and D : E : F = L : M : N  then


Example: If  A : B : C : D = 3 : 2 : 5 : 4 and D : E = 3 : 5  then find A : B : C : D : E ?





Type and Ratio Short Trick 4:

  1. First proportion       ,    a = (b x c) / d
  2. Second proportion    ,    b = (a x d) / c
  3. Third proportion      ,     c = (a x d) / b
  4. Fourth proportion     ,     d = (b x c)/ a
Example:  ? : 3 : : 15 : 9






Type and Ratio Short Trick 5:

By expiration a : b : : b : c :-

  1. First proportion       ,    a = (b^2) / c
  2. Second proportion    ,    b = (ac)^(1/2)
  3. Third proportion      ,     c = (b^2) / a

Example:Find the first proportion of 6 and 9.









Type and Ratio Short Trick 6:


If X has to divide in ratio of P and between Q has to divide into ratio of A : B, then

  1. Part of P = {a / (a+b)} x X
  2. Part of Q = {b / (a+b)} x X
  3. Difference between parts of P and Q = {(a-b) / (a+b)} x X          [where   a > b] 
Example:If 320 rs has to divide in ratio of A and between B has to divide into ratio of 3 : 5, then find part of A , part of B and difference between A and B.

Type and Ratio Short Trick 7:


If ratio of parts of P and Q is a : b and difference between there parts is X, then

  1. Part of P = {a / (a-b)} x X
  2. Part of Q = {b / (a-b)} x X
  3. Difference between parts of P and Q = {(a+b) / (a-b)} x X           [where   a > b] 
Example:The ratio between part of Amar and Suresh is 3 : 2. If part of Amar is more then Suresh by 500 rs , then find part of Suresh.








Type and Ratio Short Trick 8:

            If ratio of parts of P and Q is a : b and part of P is X, then

  1. Part of Q                  = (b / a) x X
  2. Total part of P and Q = (a + b) x X
  3. Difference between parts of P and Q = {(a-b) / a} x X 

Example:How much zinc should be added to 24 gram of copper, such that there ration will become 9:4







Type and Ratio Short Trick 9:


                     When there will be ratio of a : b : c in P , Q and R



   1. If X is part of P,


  • Part of Q     =    (b/a) x X
  • Part of R     =    (c/a) x X
  • Difference between parts of Q and R = {(b-c)/a} x X       ,[where b>c]
  • Total part of P,Q and R = {(a+b+c)/a} x X

   2. If total part of P,Q and R will be X,


  • Part of P,Q and R respectively :- a/(a+b+c) x X , b/(a+b+c) x X and c/(a+b+c) x X
  • Difference between parts of P and Q = (a-b) / (a+b+c) x X  ,    [where a>b]
  • Difference between parts of Q and R = (b-c) / (a+b+c) x X  ,    [where b>c]

   3. If difference between parts of P and Q is X,

  • Part of R     =    {c / (a-b)} x X,                           [where a>b]
  • Total part of P,Q and R = {(a+b+c) / (a-b)} x X ,   [where a>b]
  • Difference between parts of Q and R = (b-c) x X    [where a>b and b>c]
