Question

After 10 years, I will be twice as old as 5 years
ago, what is my present-age?​

Answer 1

Step-by-step explanation:

In these problems try not to calculate everything in your mind, but write them down in equations. They seem like riddles that your old great-uncle would say in a family dinner, but are simple if you think mathematically.

we assign a the age of A and b the age of B

10 years from now A will be twice as old as B

a + 10 = 2b

5 years ago A was 3 times as old as B

a - 5 = 3b

Answer 2

Answer:

10 is the answer for this question
