A number of two-digit has 3 for its unit digit and the sum of the digit is of the number itself. The number is
Explanation
Let the ten's digit be 'x'
Then, number (10x+3)+ sum of digits = (x+3)
So,
⇒ (x+3)=(10x+3)
⇒ (11x+33)=(20x+6)
= (11x-20x)=6-33
= -9x=-27
= x=3
∴ the number 33.
Hence, Option D is correct.
