Question

Jack was 15 years older than priscilla. Together their ages totalled 159 years. What were their ages?

Answer 1

Priscilla=x

Jack=x+15

sum of their ages =x+x+15=159

so,

2x+15=159

2x=159-15

2x=144

x=144/2=72

so,

priscilla is 72 and jack is x+15 which is 72+15=87

thanks

Answer 2

Solution -

Let the age of Priscilla be x yrs

So, the age of Jack be x + 15 yrs

According to Question,

x + x + 15 = 159

⇒ 2x = 159 - 15 = 144

⇒ x = 144/2

⇒ x = 72

Required Ages -

Priscilla = x yrs = 72 yrs

Jack = x + 15 yrs = (72 + 15) yrs = 87 yrs

∴ Jack's age is 87 years and Priscilla's age is 72 years
