Question

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?​

Answer 1

Answer:

you made a equation which always results in 1. then you added variables to the equation and then subtracted them which results in 0. so what ever you choose it is already decided to be 1 .

example:

{(X+5)-3}-X will always result in 2. which ever number you choose in the place of X the answer is always 2.
