Find a five-digit number in which the last number is the sum of the first, second, and third; the third is four less than the last; the fourth is two less than the last; and the first and fourth added are one less than the last. The last number is also three times the second.
By trial and error method
since its told that last digit is 3 times the second digit
means last digit is multiplication of 3
Let the last digit be 9
1.the third is four less than the last=9-4= 5
2.the fourth is two less than the last = 9-2 = 7
3.The last number is also three times the second.
4. first digit = 9-7-1 =1
5.the last number is the sum of the first, second, and third = 1+3+5= 9
Hence all condition are satisfied
Hence 5 digits are 13579
Its the possible answer
What is the four digit number in which the first digit is one-third the second, the third is the sum of the first two, and the last is three times the second?
Create a four digit number in which the first digit is one fourth of the last digit, Second digit is 6 times of the first digit, and the third digit is addition of the second digit and 3.
Find the five digit number in which the first digit is one half of the the 4 fourth digit, the second digit is one fourth of the last digit, the fourth digit is 3 times the second digit, and the third digit is the first digit plus 4.
Its a 4 digit Car Plate Number: KL45 - _ _ _ _
1. Last digit is double of First digit.
