1234/12 Dividend = 1234 and Divisor = 12. Split divisor (12) in 2 parts (1 and 2) where division will be carried using ONLY 1(new divisor) and 2 is called as flag. As flag is single digit, Split dividend in 2 parts such that 2nd part will have same number as that of flag i.e. 1 digit

Given:

A four-digit number is given.

If one digit of the number is omitted and the new number is added to the starting number, we get 1254.

To find :

The starting number.​

Solution:

Let a b c d be the starting number.

If one digit of the number is omitted and the new number is added to the starting number, we get 1254.

The new number is 0 a b c

a = 1

d + c = 4

c + b = 5

a + b = 2

1 + b = 2

b = 2 - 1

b = 1

c + b = 5

c + 1 = 5

c = 5 - 1

c = 4

d + c = 4

d + 4 = 4

d = 4 - 4

d = 0

The Starting number is 1140

The new number is 0114

If the new number is added to the starting number, we get 1254.

So, 1140 + 114 = 1254

Final answer:

The starting number is 1140.
