Ratio based problem are very important for banking exams or ssc exams all type competitive exams, One or two problems are given in paper based exam or online exams. Here is some problems are given with solution including ratio shortcut tricks which are given in exams.
We elaborate one example here, some amount is given this amount are divide into persons and find the amount of one or two persons. Some examples are given to find the mean term of example 2. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below given some more example for your better practice.
In a town, 20% of the men are same in numbers as 1/4th of the women. What would be the ratio of men and women in that town?
( 20 / 100 ) Men <=> ( 1 / 4 ) Women
Men / Women = 4 / 5
Men : Women = 4 : 5
In a school, the number of ratio of boys and girls is 4 : 9. After inclusion of 32 new girls, the ratio become 4 : 17. How many boys were present in the school ?
68x = 36x + 128
x = 4
So, the number of boys in the school is (4 x 4) = 16.
In a school ratio of boys and girls is 9 : 6 and if there present 180 boys, than find the total number of students in the school.
Then, 9x = 180
x = 20
So, total number of students is 15x = (15 x 20) = 300.
Share Rs.4200/- among Joy, Sanjay and Bijoy in the ration 2 : 4 : 6. Find the amount received by Sanjay.
4 / 12 X 4200 = 1400
So, the Amount received by sanjay is 1400.
Find the mean proportional between given two number that is 64 and 49.
So, the mean proportional is 56.
Rs.385/- were divided among P , Q , R in such a way that P had Rs 20 more than Q and R had Rs 15 more than P. How much was R’s share?
So, We can say that P gets ( x + 20 ) and R gets ( x + 35 ).
Now, x + ( x + 20 ) + ( x + 35 ) = 385
3x = 330
x = 110
So, R’s share is ( 110 + 35 ) = Rs.145/-.
Rs.1210/- were divided among three person P, Q, R in the ratio of P : Q = 5 : 4 and Q : R = 9 : 10. So, what amount will R gets?
Q : R = 9 : 10 = ( 9 x 4 / 9 ) : ( 10 x 4 / 9 ) = 4 : 40 / 9
So, P : Q : R = 5 : 4 : 40 /9 = 45 : 36 : 40
Sum of ratio terms is = ( 45 + 36 + 40 ) = 121
So, R’s share amount is ( 1210 x 40 / 121 ) = Rs.400/-.
Rs.64000/- are divided among three friends in the ratio of 3 / 5 : 2 / 1 : 5 / 3. The will be the share of the second friend?
So, the Share of the second friend will be ( 64000 x 30 / 64 ) = 30000.
Which of the following ratio is the greatest?
7 : 15, 15 : 23, 17 : 25, 21 : 29
15 / 23 = 0.652
17 / 25 = 0.68
21 / 29 = 0.724
So, 0.724 is greatest and therefore, 21 : 29.
What number has to be added to each term of 3 : 5 to make the ratio 5 : 6.
then, ( 3 + x ) / ( 5 + x ) = 5 / 6
6 ( 3 + x ) = 5 ( 5 + x )
x = ( 25 – 18 ) = 7
So , the number to be added is 7.
On dividing a sum of Rs.832/- between Paul and John in the ratio 3 : 5, what will be their shares?
Paul’s share will be ( 832 x 5 / 8 ) = Rs.520/-
John’s share will be ( 832 x 3 / 8 ) = Rs.312/-
So, their shares are 312 and 520.
A certain amount was divided between A and B in the ratio of 4 : 3. If B’s share was Rs.4800/-, what wsa the total amount?
And sum of ratio terms is = ( 4 + 3 ) = 7
Now, B’s share is 4800
then sum of share amount is = ( 7 / 3 x 4800 ) = 11200.
The Salary of Three friend A, B, C are divided into ratio 5 : 6 : 8. If the increment has given of 10%, 20%, 25%, then find the new ratio of three friend salary?
Now the increment of new salary of A is 10% = 110 / 100
B is 20% = 120 / 100
C is 25% = 125 / 100
A,s new salary is 110 x 5X / 100 = 55X / 10
B,s new salary is 120 x 6X / 100 = 36X / 5
C,s new salary is 125 x 8X / 100 = 10
So, the new ratio is 55X / 10 : 36X / 5 : 40X / 4.
