                       A    :     B : C
Capital → 45000:80000:120000
Time(year) →  2    3/2     1
Profit → 90  :    120    :  120
                     3    :    4    :    4
∴ Required ratio of profit = 3 : 4 : 4

Let C subscribes the business = Tk. x
                          A : B : C
Capital → (x + 12000) : (x + 5000) : x
Note: Profit would be divide in the ratio of their capitals
According to the question,
⇒(x+12000)+(x+5000)+x = 47000
⇒ 3x+17000= 47000
⇒ 3x = 30000
⇒ x = 10000
                         A : B :C
Capital→22000:15000:10000
Profit→ 22 : 15 : 10
(22+15+10) units = 4700
1 unit=4700/47=100
Share of C = 10 units = 10×100 = Tk.1000

Let the number of boys and girls be 4x and 5x respectively.
Then,
4x/(5x−100)= 6/7
⇒28x = 30x−600
⇒2x=600
⇒x=300
∴Number of boys=4×300=1200

                   A      :     B
Income     9    :    7
Expense       4    :    3
Income - Savings + Expenditure
∴(9x−200)/(7x−200) = 4/3
⇒27x−600 = 28x−800
⇒x=200
Sum of weekly income
= 9x+7x = 16x
= 16×200 = Tk.3200

Quantity of milk and water in the 36 liter mixture
27 liter milk and 9 liter water

Clearly, the numbers which have 1 or 9 in the unit's digit, have squares that end in the digit 1. Such numbers from 1 to 70 are 1, 9, 11, 19, 21, 29, 31, 39, 41, 49, 51, 59, 61, 69.
Number of such number =14
Required percentage = (14/70)x 100% = 20%

Let the number be x
Then, 64% of x = 2592
⇒ 64 x 100 = 2592
⇒ x = (2592×10064)
⇒ x = 4050
∴ 88% of 4050 = (88/100 × 4050) = 3564

Let the original price be Tk. 100
New final price :
= 120% of (75% of Tk. 100)
= Tk. (120/100 × 75/100 ×100)
= Tk. 90
∴ Decrease = 10%

Let the total capital = 1200
According to the question,
one-fourth of 1200 = 300, two third of 1200 = 800, remain 100
Interest on 300 = 3% of 300 = 9
Interest on 800 = 5% of 800 = 40
Interest on 100 = 11% of 100 = 11
Total interest = (9 + 40 + 11) = 60
Required percentage :
= 60/1200 × 100
= 5%

Currently the mixture is in ratio of A/B: 7:5
=> This means fraction of A in the solution: 7/12
=> Fraction of B in the solvent: 5/12
=>New concentration of A= 7-(7/12)9
=>New concentration of B= 5-(5/12)9+x
=> (7-(7/12)9)/(5-(5/12)9+x) = 7/9
=>x=21

Let the weight of full bottle be 6kg.
Therefore, weight of empty bottle is 1kg and that of water is 5kg.
If x% of water is removed, the weight of the bottle becomes 2kg.
Therefore, the amount of water removed is 4kg.
% of water removed = 4/5 × 100 = 80%

So amount of acid = 2/ 2+1 × 90 = 60L
Amount of water = 90 - 60 = 30L
To make acid to water ratio = 1:2, we simply need
To make water double of acid.
By direct observation, we can say that we should have 60L × 2 = 120L make the required ratio
We have 30L, we need (120-30) = 90L more water

Let 3rd type sugar rate be Tk. S
Quantity ratio = 2:1:3
This means if we take 2kg of Type 1 and 1 kg of Type 2, then we must take 3kg of Type 3.
Also, the mix will have 2kg+1kg+3kg 6 kg quantity.
(145 × 2) + (165 × 1) + (3 × S)= 6 × 180
S = Tk. 208.33 per kg = 3rd type price per kg

Since both cans are similar, let their capacity be 100 liters.
Can 1 has 100 liters water
And Can 2 has 50 liters wine and 50 liters of water
When mixed in steel vessel we get, 100+50 ISO liters water and SO liters wine
So water : wine = 3:1
