Question

Sarah is twice as old as her youngest brother. If the difference between their ages is 15 years. How old is her youngest brother?​

Answer 1

Hi mate

Here is your answer

Let Sarah's age be x

Then her brother's age will be x/2

Therefore x - x/2 = 15,

solving the equation:                

 2x - x = 30                 

  x = 30

Hence Sarah is 30 years old and her brother is 15 years old.
