We know that, the collection of programs which performs specific tasks in a computer is called as software. Software in a computer is of two types. They are :

1. Aplication Software

1 TB  >  1 GB  >  1 MB  >  1 KB

1 Tb (Tera Byte) = 1024 GB

1 GB (Giga Byte) = 1024 MB

1 MB (Mega Byte) = 1024 KB

1 KB (Kilo Byte) = 1024 Bytes

1 Byte = 8 Bit

Hence, largest unit of information is TB (Tera Byte) and smallest unit of information is Bit.

Makaibari is the world's first tea factory and was established in 1859 in Darjeeling, West Bengal. 

It is most expensive tea in India which costs around 1.12 lakhs for 1 kg of tea.

They both are used to replace characters in a string

$$\begin{gathered} 32oF \\ We know that \\ T(°F) = T(°C) × 1.8 + 32 \\ 32(°F) = 0(°C) \end{gathered}$$

We can make an equation:

3(100000 + x) = 10x+1

(Why? Well, adding 100000 puts a 1 at the front of a five-digit number, and multiplying by 10 and adding 1 puts a 1 at the end of a number)

Solving this gives:

10x+1 = 3(100000 + x)
10x+1 = 300000 + 3x
10x = 299999 + 3x
7x = 299999
x = 299999/7 = 42857

The answer is 42857 (142857 is three times smaller than 428571).
