Question

Paul is 12 years old. He is thrice as old as his brother.How old will paul be when he is thrice

Answer 1

Answer:

She will 20 years old.

Step-by-step explanation:

Let the age of her brother = x,

⇒ Her age = 3x,

According to the question,

3x = 12,

⇒ x = 4,

Since, when the age of brother is three times of his present age,

Then, his new age = 3 × 4 = 12 years,

The time = 12 - 4 = 8 years,

⇒ After 8 years his brother is 3 times of his present age,

Since, after 8 years the age of Paul = 12 + 8 = 20 years,

Hence, she will 20 years old.
