Question 1139224
when you were 14 years old, your sister was 1/4 your age.
that makes her 14/4 = 3.5 years old when you were 14 years old.


she is now 21 years old.
that makes her 21 - 3.5 = 17.5 years older than when she was 3.5 years old.
that makes you 14 + 17.5 = 31.5 years old now.


your solution is that you are now 31.5 years old.
