Question

My younger brother's age today is 3 times what it will be 3 years from now minus 3
times what his age was 3 years ago. If my brother is 5 years younger than me, what
is my present age?​

Answer 1

Answer:

Let my younger sister be x years old at present.

After 3 years, her age =(x+3)

Before 3 years, her age was =(x−3)

ACQ,

x=3(x+3)−3(x−3)

⇒ x=3(x+3−x+3)

⇒ x=2×6

⇒ 18

Therefore, 18 years is the present age of my younger sister.
