Question

When a man is asked for his age, he replied, "my age is 140% of what it was 10 years ago. what is the age of the man?"?

Answer 1

The age of the man is 35

Answer 2

Given,

A man's age is 140% of what it was 10 years ago.

To find,

The age of the man.

Solution,

We can simply solve this mathematical problem using the following process:

Let us assume that the present age of the man is x years.

So, the age of the man before 10 years is (x-10) years.

Mathematically,

p% of a number A is calculated as follows:

p% of number A = (p/100) × A

{Statement-1}

According to the question;

The man's present age = 140% of the age of the man before 10 years

=> x years = 140% of (x-10) years

=> x = (140/100) × (x-10)

=> 100x = 140x - 1400

=> 140x - 100x = 1400

=> 40x = 1400

=> x = 1400/40 = 35

=> present age of the man = 35 years

Hence, the present age of the man is 35 years.
