उत्तर
Let the number be x.
If we subtract 27 from x i.e. (x – 27) and subtract x from 73 i.e. (73 – x), we get the same result.
Therefore, we get the following equation
x – 27 = 73 – x
⇒ x + x = 73 + 27 ...[Transposing (– 27) to RHS and (–x) to LHS]
⇒ 2x = 100
⇒ `(2x)/2 = 100/2` ...[Dividing both sides by 2]
⇒ x = 50
Hence, the required number is 50.
