## Detailed Solution

Given:

A vessel contains a mixture of P and Q in the ratio of 5 : 3.

16 liters of the mixture is taken out and 5 liters of P is poured in.

The new mixture has ratio of P to Q as 11 : 6.

Calculation:Short Trick: total original quantity of mixture = 80 + 16 = 96 liters

Detailed Solution:

P = 5x, Q = 3x

The quantity of P and Q in 16 liters of the mixture,

Quantity of P = (16 × 5x)/8x = 10

Quantity of Q = (16 × 3x)/8x = 6

Now, 5 liters of P poured in and then ratio becomes 11 ∶ 6

(5x - 10 + 5)/(3x - 6) = 11/6

(5x - 5)/(3x - 6) = 11/6

Solve, x = 12

So total mixture originally = 8x  = 8 × 12 = 96 liters

Say, initially there was p litres of P & q litres of Q.

Total initial volm = p+q litres

In the taken 20 litres there were 12 litres of P & 8 litres of Q.

After taking 20 litres of Q instead, there were p-12 litres of P & q-8+20 litres of Q. This ratio is 1:4.

From the initial condition,

p/q = 3/2 Or, p= 3q/2 =1.5q

From the final condition,

(p-12)/(q+12) = 1/4 Or, 4p-48 = q+12 Or, p= (q+60)/4 Or, 4*1.5q = q+60 Or, 6q = q+60 Or, 5q = 60 Or, q = 12 litres.

p = 1.5*12 = 18 litres.

Statement of the given problem,

A vessel contains a mixture of liquid P and Q in the ratio of 3 : 2. When 20 litres of the mixture is taken out and replaced with 20 litres of liquid Q, the ratio changes to 1 : 4. How many litres of liquid P were initially present in the vessel?

Let PV & QV denote the amounts (in L) of P & V present in the initial mixture respectively.

Hence from above data we get following relations,

PV : QV = 3 : 2 or QV = (2/3)*PV

[PV - 3*20/(3 + 2)] : [QV - 2*20/(3 + 2) + 20] = 1 : 4

or (PV - 12) : (QV - 8 + 20) = 1 : 4

or (PV - 12) : (QV + 12) = 1 : 4

or 4*PV - 48 = QV + 12

or 4*PV Related questions

Vasudevan A.N.S.

Let “V”- litres of milk be in the container.

After removing 20- litres of the mixture the volume of Q - in the mixture= (V-20) x 3/5

On adding 20- Litres of Q- to the mixture, the volume of pure Q in the new mixture =(V-20)3/5 + 20 .

This is now equal to =Vx 4/5

So (V-20)3/5 + 20= Vx4/5

So V/5= (20–12)= 8 So V= 40 Litres

Therefore total volume of the mixture =40 litres

So volume of “P”- in the initial mixture = 40 x (2/5)
