Question 1148266: If three years ago Simon was three years old in four years time he would be twice the age of his sister Sophie. How old will sophie be in four years time
From the condition, Simon is 6 years old now.
In 4 years, he will be 6+4 = 10 years old.
Hence, in 4 years Sophie will be 5 years old.
It means that Sophie's present age is 1 year.
