Question

A man is x years old now. In 10 years time he will be twice as old as he was 5 years ago. How old will he be in 10 years time

Answer 1

Explanation:

Let's solve this step by step:

1. Let's represent the man's current age as "x".

2. In 10 years, his age will be "x + 10".

3. "He will be twice as old as he was 5 years ago" means that his age 5 years ago was half of his current age.

4. So, his age 5 years ago was "x/2".

5. In 10 years, his age will be "x + 10".

6. According to the given information, his age in 10 years will be twice his age 5 years ago:

x + 10 = 2 * (x/2)

7. Simplifying the equation:

x + 10 = x

8. Subtracting "x" from both sides of the equation:

10 = 0

9. We have reached an incorrect equation, which means there is no solution that satisfies the given conditions.

Therefore, we cannot determine how old the man will be in 10 years based on the given information.

Answer 2

answer: 30 years old

PRESENT AGE= X
AGE AFTER 10 YEARS= X+10
AGE 5 YEARS AGO= X-5
X+10= 2(X-5)= 2X-10
X= 20
MAN WILL BE 30 YEARS
x + 10 = 2(x - 5)
x + 10 = 2x - 10
20 = x
He is 20 years old now.
In 10 years, he will be 30 years old
