Answer :
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.
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
