Sneha did a math magic with her friend Kriti. She asked her to think of a two-digit
number. Then she asked her to add the digits of the number and then multiply the sum
by 5. She asked her to add 5 to the product and multiply the result by 2. Then she
asked her to divide the result. by 10 and to subtract the sum of the digits from this
number. Sneha told Kriti that number left is 1. Kriti is amazed. Can you help Kriti to
understand this magic?
