 Question

The ratio between father and son age is 17 : 7.

6 years ago,  the ratio was 3  : 1.

What is the current age of father and son  ?? 

Answer

It is given that present age ratio of father and son is 17 :  7.

Let the age of father  17x

Age of son  7x

It is also given that 6 years ago, the ratio of their age was  7 :  1

Let the age 6 years ago, 

Father  17x  - 6

Son         7x  - 6

. 

Their age ratio  3 :  1

( 17 x  -  6 )  :  (  7 x  - 6  )  =   3 : 1

17 x  - 6              3

--------------     =   -----

7 x  -  6                1

Cross multiplying we get

17  x  -  6  =  3  (  7 x  -  6  ) 

17  x  -   6   =   21  x   -   18

21 x  -  17  x   =  - 6  + 18

4 x  =  12

X  =   3

At present, 

Son's age is   7 x  =  7  ×  3  =  21  years

Father's age is   17  x =  17  ×   3  =  51  years

Benefits of kneading dough with milk

 In Indian households, women usually knead dough with water.  Even my mother does like that  !!!

But recently in a cookery show, I watched the host kneading dough with milk instead of water  !!!

Benefits of kneading dough with milk instead of water   -------

1.  Using milk in dough adds a mild richness that improves the taste. Slight creaminess adds the flavour  !!!

2. Milk helps to create a softer texture , as its fats and proteins make the dough more tender.

3.  The natural sugars in the milk gives better brown colour when cooking.

4.  Milk improves moisture retention so that dough stay fresh for longer time.

BE CAUTIOUS   ------

1.  Milk burns faster than water.  So it turn the dough brown too fast.

2.  Milk used in dough ferments faster. It can go sour if it is kept in room temperature for long hours.

      Refrigeration is required.

3.  Milk is 87% water. Milk is little heavy compared to water and it is better to use little less.
