Answer 1

Hint: In the given question, we have to find out a five-digit number. There is some information given. To solve this question, first note down the places using Indian number system such as –
Ten thousand, Thousands, Hundred, Tens, Ones.
Read the given information carefully and write down the numbers according to the question. It is a simple way which can solve this question without making any mistakes

Complete step-by-step answer:
According to hints write Indian number system position as asked number is of five digits.
Firstly, it is given that, in Indian place, the digit is $'2'$.So, writing down this value to a place of hundred.
Again, it is given that , in one’s place the digit is twice that of in hundreds place, i.e. no. in one’s digit $ = 2 \times 2 = '4'$.The number has no digits in thousand’s place, i.e. digit in thousand’s place is $0$.The digit in ten thousand place is sum of digits of hundred’s place & one’s place, i.e. $4 + 2 = 6$.
The digit in ten’s place is (number in hundreds place $ - 1$).
i.e. the digit is $(6 - 1) = 5$.
$\therefore $ Resultant number of five digit is,
TTH TH H T O
 $6$ $0$ $2$ $5$ $4$
$\therefore $ $60254$ is a resultant number

Note: We can also take the international number system in place of Indian number system because, first $5$ digits or place – Ten thousand, Thousands, Hundreds, Tens, Ones are the same in both cases. Number systems are used for formation of any number. In this question, we too used this for solving its answer.
