Question

Ann is 3 times old as his cousin and the difference of their ages is 18. How old is Ann?

Answer 1

18 years

Step-by-step explanation:

Let age of Ann's cousin be x

Then,

Age of Ann = 3x

Now, their difference of their ages is 18

Then, we can form the following equation:

$3x = 18 \\ x = \frac{18}{3 } \\ x = 6$

Now, we got the value of 'x' means we got the age of Ann's cousin (ie) 6 years

Therefore,

Age of Ann is 3x (ie) 3 × 6 = 18

Thus, the age of Ann is 18 years

Answer 2

❄️ Answer:-

Ann's age = 18 years

________________________

❄️ Given:-

• Ann is times old as his cousin
• The difference of their ages is 18
• How old is Ann?

❄️ Solution:-

Let the age of cousin be = x

Let the age of Ann be = 3x

Given that the difference between their age is 18.

So, the equation which is formed is :

3x – x = 18

Now we are solving for x.

3x – x = 18

→ 3x = 18

→ x = 18/3

→ x = 6

So,

Cousin's age = x = 9 years

and, Ann's age = 3x = 3(6) = 18 years
