HELP PLSSS

max is m years old. His sister is twice as old as he is. The sum of their ages is 27. How old is Ahmed and his sister?

Answer 1

Age of Ahmed is 9 years

Age of Ahmad's sister is 18 years

Explaination :

In the question it is given that Ahmed is of m years.

• Age of Ahmed = m years

Her sister is twice as old as he.

• Age of Ahmad's sister = 2 × m = 2m years

Now in the question it is given that sum of their ages is 27. So lets add the age of Ahmed and his sister and keep it equal to 27 inorder to get the value of m.

Age of Ahmed + Age of his sister = 27

m + 2m = 27

3m = 27

m = 27 / 3

m = 9

• Therefore, value of m is 9..!!

★ Age of Ahmed:-

Age of Ahmed = m

Age of Ahmed = 9 years

★ Age of his sister:-

Age of Ahmad's sister = 2m

Age of Ahmad's sister = 2 × 9

Age of Ahmad's sister = 18 years

Answer 2

Given ,

Ahmed's age = " m " years.

Also ,

age of Ahmed's sister = 2 × m = 2m years

According to Question ,

age of ahmed + age of his sister = 27

`\bold{m + 2m = 27 }\\ \bold{3m = 27 }\\ \bold{m = \cancel{(27)/(3) }} \\ \\ \fbox\blue{m = 9}`

therefore ,

age of Ahmed = 9 years.

age of Ahmed's sister = 2m = 2 ( 9 ) = 18 years.
