Math, asked by debapriyabanerjee13, 1 month ago

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?​

It is simple...just follow the instructions.

Let the two digit number be 25.

A.T.Q.

2 + 5 = 7 ----(1)

7*5 = 35

35 + 5 = 40

40*2 = 80

80/10 = 8

8 - 7 = 1 [ FROM (1)]

So , here is your answer .... it is nothing just calculation. You can pick any two digit numbers.

Hope it will help.
