The logic in the challenge is

 81x6 = 9x6 = 54

144x7=84

Similarly, 64x8 = 8x8 = 64.

Number of positive integral solutions =  n-1Cr-1 = C220 = 190

The storage capacity is measured in bytes, kilo bytes, mega bytes, giga bytes and tera bytes. The largest unit of storage is Tera bytes.

Given ratio of initial mixture of milk and water in Q = 5 : 3

Let the initial quantity of mixture in vessel Q = 8x

Let quantity of Milk = 5x and

Let quantity of water = 3x

According to the question,

5x + 10 x 353x + 10 x 25 = 85

=> 25x + 30 = 24x + 32

=> x = 2

Required Initial quantity of milk = 5x = 5 x 2 = 10 lit.

1λ=1λ1+1λ2

1355=1680+1λ2

1λ2=680-355680×355

⇒λ2=743nm.

Assume the family has X girls and Y boys, according to the question,
we can have 2 equations:
X-1=Y, 2(Y-2)=X.
Solve the equations, we get X=4, Y=3.
