Answer:
The 8 digit number is 7,08,04,599
Step-by-step explanation:
Given conditions are
(a) I am 8 digit number.
(b) The last two digits are the predecessors of the smallest 3-digit number.
(c) The digit in the lakh place is twice the digit in the thousand place and multiple of 4.
(d) The digit is ten thousand place and ten lakh place is same and is equal to the difference between last two digits.
(e) The digit in the crore place is equal to the number of days in a week.
(f) The digit in the hundred place is your class 5. what is the number?
To find,
The 8 digit number
Solution:
Let the number be X,XX,XX,XXX
The smallest three digit number = 100
The predecessor of the smallest three-digit number = 99
Hence the last two digits of the 8 digit number = 99
Then the number is X, XX, XX, X99
(e)The digit in the crore place is equal to the number of days in a week
The number of days the week = 7, then the digit in the crores place is 7
The number becomes 7, XX, XX, X99
(f) The digit in the hundred place is your class 5
Since the digit in the hundred's place is 5, the number becomes 7, XX, XX,599
(d) The digit is ten thousand place and ten lakh place is same and is equal to the difference between last two digits.
The difference between the last two digits = 9-9 = 0
Hence the digit in the ten thousand place and ten lakh place is same = 0
Hence the number becomes 7,0X,0X,599
(c)The digit in the lakh place is twice the digit in the thousand place and multiple of 4
The digits that are multiples of 4 are 4 and 8
The digit in the lakhs place is 8 and the digit in the thousand's place is 4
Hence the number becomes 7,08,04,599
Hence the required 8 digit number is 7,08,04,599
