Question

Pat was 32 when his daughter Emma was born, and 36 when his son Andy was born. If the sum of the tree ages is now 100, how old is Andy Now?

Answer 1

Answer: Andy is 20 years old

Let x be Andy’s current age
Andy: x
Emma: x+4 because she is 4 yrs older than her lil bro andy and we know this cuz their dad was 4 yrs older when Andy was born than when Emma was bro
Pat: 36+x cuz he is 36 yrs older than his son

x + (x+4) + (36+x) = 100
3x + 40 = 100
3x = 60
x = 20

So Andy is now 20 years old
Emma’s age is 20 + 4 so she is 24 years old
Pat’s is 20 + 36 = 56 years old

I hope this helps :)
