Let the numbers be x and 5x.
If 21 is added to both the numbers, then first new number = x + 21
and, second new number = 5x + 21
Case I. When first new number is twice the second new number.
Then,
x + 21 = 2(5x + 21)
∴ x + 21 = 10x + 42
∴ x – 10x = 42 – 21 . . . . [Transposing 10x to L.H.S. and 21 to R.H.S.]
∴ – 9x = 21
∴ {tex}x = - \frac{{21}}{9}{/tex}. . . . [Dividing both sides by –9]
∴ {tex}x = \frac{{ - 21 \div 3}}{{9 \div 3}}{/tex}
∴ {tex}x = - \frac{7}{3}{/tex}
∴ {tex}5x = \left( { - \frac{7}{3}} \right) \times 5 = - \frac{{35}}{3}{/tex} hence the numbers are {tex} - \frac{7}{3}{/tex} and {tex} - \frac{{35}}{3}{/tex}.
This case is inadmissible as the required numbers are positive.
Case II. When second new number is twice the first new number.
Then, 5x + 21 = 2(x + 21)
∴ 5x + 21 = 2x + 42
∴ 5x – 2x = 42 – 21 . . . . [Transposing 2x to L.H.S. and 21 to R.H.S.]
∴ 3x = 21
∴ {tex}x = \frac{{21}}{3}{/tex} . . . . [Dividing both sides by 3]
∴ x = 7
∴ 5x = 5 × 7 = 35 hence, the numbers and 7 and 35.

A fraction is written in the form of m/n , where n is not 0 and m & n are natural numbers. For example: 12/23, 10/32, 12/10, 4/21.
A rational number can also be written in the form of m/n , where n is not 0 and m & n are integers. For example: 15/7, -18/13, 3/-7, -6/-12.
All Fractions can be termed as Rational Numbers, however, all Rational Numbers cannot be termed as Fractions. Only those Rational Numbers in which ‘m’ and ‘n’ are positive integers are termed as Fractions.

The sliding friction is less than static friction because of the interlocking of irregularities in the two surfaces. When the object starts sliding the contact points on its surface, do not get enough time to lock into the contact points on the floor.
So the sliding friction is slightly less than the static friction.

Metals react with acids to produce hydrogen gas. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. It is this hydrogen gas that burns with a pop sound.
- For instance, Magnesium reacts with dilute hydrochloric acid to form magnesium chloride and hydrogen.
Mg + 2 HCl → MgCl2 + H2

The upper layer of earth is called soil in which crop plants are grown. Soil provides minerals, water, air, humus and anchorage to the plants. Preparation of soil is the first step in cultivating a crop for food production. The soil is prepared by ploughing, levelling and manuring. This makes the soil fertile.
