Given:

25 consecutive natural numbers

Average of the last 13 numbers = 39

Formula Used:

Average of an arithmetic series = (First term + Last term) / 2

Calculation:

Let the first number of the 25 consecutive natural numbers be a.

Then, the last 13 numbers are a + 12, a + 13, ..., a + 24 .

The average of these 13 numbers is given by:

$\frac{(a + 12) + (a + 24)}{2}$ = 39

⇒$\frac{2a + 36}{2}$ = 39

⇒ a + 18 = 39

⇒ a = 21

The 25 consecutive numbers are 21, 22, ..., 45.

The average of these 25 numbers is given by:

$\frac{21 + 45}{2}$ = 33

The average of all 25 numbers is 33.

Concept:

Fermentation:

• The incomplete oxidation of glucose is achieved under anaerobic conditions by sets of reactions where pyruvic acid is converted to CO2 and ethanol is known as fermentation.
• The enzymes, pyruvic acid decarboxylase and alcohol dehydrogenase catalyse these reactions.

Explanation:

Milk to curd process:

• Curd or yoghurt is made from milk through the fermentation process.
• Casein, a type of globular protein, is present in milk.
• Lactic acid bacteria and casein undergo a chemical reaction that results in the curd.
• A wide range of bacteria, including Lactobacillus acidophilus, Lactococcus lactis, Lactococcus lactis cremoris, and others, may be present in curd.
• Milk to curd formation is a slow process.
• A curd-forming bacteria takes 5 to 6 hours to change milk into curd.
• This change is permanent and irreversible because this curd cannot be converted back into milk.

Thus, the change from milk to curd is a slow and permanent change.
