A wine connoisseur had Rs. 5000. She used some of that money to buy two wine bottles, and then sold them both for Rs. 2400 each. She made a profit of 50% on one and a loss of 20% on the other. How many rupees does she have left now?

(i) 2

(ii) 4

(iii) 3

We know that numbers are often rounded to avoid reporting insignificant figures.

(i)The First rule is that all non-zero digits are considered as significant: 1, 2, 3, 4…….

(ii)Then the second rule is Zeros between non-zero digits are also considered as significant: 102, 200005, 25020…..

(iii)Now, the third rule can be given as: Leading zeros are never significant: 0.02, 001.887, 0.000515.

(iv)Fourth and the most significant rule is that in a number with or without a decimal point, trailing zeros which are on the right of the last non-zero digit are significant if they are justified by the precision of their derivation: 252,0000; 5.02121000; 6.900; 42.697800

On basis of these rules, we can say that

1. 25.42 have 2 significant figures.
2. 0.004672 have 4 significant figures, as zeroes before the non-zero numbers are considered insignificant.
3. 35.320 have 3 significant figures.

Answer:

250 meters is one part of 4 parts of 1 kilometer and the corresponding fraction is [tex]\frac{1}{4}[/tex] .

Step-by-step explanation:

We know that,

1 km = 1000 m

1000 meters constitute one kilometer.

We need to find the part of 250 meters in 1 kilometer.

The equivalent fraction is,

[tex]\implies \dfrac{250}{1000} = \dfrac{1}{4}[/tex]

To get the simplified fraction we removed the common factors of 250 and 1000.

Answer:

The part of 250m in 1 km is 1 in 4.

Step-by-step explanation:

1 km= 1000 m

The part of 250m in 1 km

[tex]= \frac{250}{1000} \\=\frac{25}{100} \\=\frac{25 \div 25}{100 \div 25} \\==\frac{1}{4}[/tex]

The part of 250m in 1 km is 1 in 4.

Explanation:

Giuseppe Mazzini was an Italian revolutionary and a patriot. Metternich was an Austrian diplomat.

Metternich described Mazzini as ‘the most dangerous enemy of our social order’ because of the following reasons:

1. Mazzini’s vision of a democratic republic frightened the conservatives.

2. Mazzini was the founder of Young Italy, and he believed in liberal nationalism.

3. He also founded the underground society called Young Europe in Berne.

4. These two societies aimed at uniting several states and kingdoms into one republic.

5. He wrote many essays that brought injustice to common people such as artists, professionals, peasants, etc., to the limelight.

Many underground societies were set up in Germany, Switzerland, and Poland which inspired young members to revolutionary activities. Hence, Metternich uttered Mazzini as the most dangerous enemy.
