Show Answer Show How to Solve Open Rough Workspace
P’s share: 75840 x 3 / 10 = 22752
Q’s share: 75840 x 7 / 10 = 53088
Thrice of the P’s share: 22752 x 3 = 106176
Twice of the Q’s share: 53088 x 2 = 68256
Difference: 106176 – 68256 = 37920

In a bottle mixture of 80 liters and the ratio of milk and water is 3 : 2. If this mixture ratio is to be 2 : 3. What is the quantity of water to be further added?
Show Answer Show How to Solve Open Rough Workspace
New Ratio required 2 : 3.
Let, X water to be added
Now, Milk : Water is = 48 : (32 + X)
= 48 / (32 + X)
Now, 48 / (32 + X) = 2 : 3
48 / (32 + X) = 2 / 3
2X = 144 – 64
X = 80 / 2
= 40 liters.
The ratio between the number of Men and Women in a society is 31 : 23. When 75 more women are added in the society, this ratio becomes 124 : 107. How many more women should be added in the society in order to make the number of men and women be equal?
Show Answer Show How to Solve Open Rough Workspace
So, the number of women in society after added
= 20 x 23 + 75 = 535.
So, the number of men in society after added
= 31 x 20 = 620.
Number of more women is = 620 – 535 = 85.
In a liquid mixture of 60 liters, the ratio of milk and water is 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is?
Show Answer Show How to Solve Open Rough Workspace
New ratio required = 1 : 2
Let, quantity of water to be added further be X liters.
Milk : Water = 40 / ( 20 + x )
Now,
40 / ( 20 + x ) = 1 / 2
20 + x = 80
x = 60 liters
So, 60 liters of water to be added further.
20% alcohol present in a 15 liters mixture and rest of water. If 3 liters of water be mixed with it, the percentage of alcohol in the new mixture would be?
Show Answer Show How to Solve Open Rough Workspace
New quantity of mixture = ( 15 + 3 ) = 18 liters.
Percentage of alcohol in new mix is = ( 3 x 100 / 18 ) % = 50 / 3.
A liquid mixture contain alcohol and water in the ratio of 4 : 3. If 5 liters of water is added to the mixture the ration becomes 4 : 5. Find the quantities of alcohol in the given mixture?
Show Answer Show How to Solve Open Rough Workspace
Quantity of alcohol = ( 4 x 2.5 ) = 10 liters.
If the ratio of milk and water is 3 : 2 in a mixture of 80 liters. If this ratio later to be 2 : 3, Then what quantity of water to be added more?
Show Answer Show How to Solve Open Rough Workspace
48 / ( 32 + x ) = 32
2x = 80
x = 40
Quantity of water to be added more is 40 liters.
In a mixture of 25 liters has contains 40% milk and remaining is water. If 5 liters of water mix with it, then what would be the new percentage of milk in mixture?
Show Answer Show How to Solve Open Rough Workspace
new mixture quantity = ( 25 + 5 ) = 30 liters.
10 x 100 / 30 = 100 / 3 liters.
So, new percentage of milk in mixture is 100 / 3 liters.

thank u
sir inQ3 ratio of cu: zn is 9:3 so weight of cu must be more than Zn
pls explain it
sir plz tell me how to solve if a:b=2:3, b:c=4:5 c:d=6:7 what is the ratio of a:b:c:d with short method
A:B=m:n
B:C=p:q
C:D=r:s
A:B:C:D=mpr:npr:nqr:nqs
hi just arrange the words horizontally as a:b:c:d
1. a:b – 2:3
2. b:c – 4:5
3. c:d – 6:7
a b c d
2 3
4 5
6 7
a = 2*4*6 = 48
b = 3*4*6 = 72
c = 3*5*6 = 90
d = 3 *5*7 = 105
a:b:c:d = 48:72:90:105 after simplifying = 16;24;30;35
first b:c and c:d value take it,
4:5 and 6:7
then common value of =c to l.c.m
5&6=30 so convert the value of c
4*6:5*6and6*5:7*5
24:30and 30:35,
so c is common value=30
so, b:c:d=24:30:35
then,take it a:b and b:c:d
2:3 and 24:30:35
then, common b value 3 and 24 l.c.m in 24,
so, 2*8:3*8and 24*1:30*1:35*1
then,16:24 and 24:30:35
common value of b=24,
ans,a:b:c:d=16:24:30:35
Hi,
Can you please explain the logic if quantity of liquid is replaced instead of added so that the proportion of mixture gets inverse.
there are 465 coins.1rupee,50paise,25paise.there values are in ratio 5:3:1.number of each coins respectively are?
5*1:3*2:1*4 = 5:6:4 => this is ratio of no of coins each have……………..now add 5+6+4=15…………..divide 15 with total no of coins that is 465. We get 31 now multiply 31 to each ratios that is 5*31:6*31*4*31= 155:186:124 this is no. Of individual coins of 1 rs,50p, and 25p
