Question

anu is 4 years older than sunil. eight years ago anu was three timea sunils age. find the age of anu

Answer 1

Solutions :-

Let the age of Sunil be x
Anu's age = x + 4

Anu was three times Sunil's age 8 years ago,

A/q

⇒(x+4) - 8 = 3(x-8)
⇒ x - 4 = 3x - 24
⇒ x - 3x = -24 + 4
⇒ -2x = -20
⇒ x = -20/-2 = 10

Hence,
Age of Sunil = x = 10 years
Age of Anu = x + 4 = (10 + 4) years = 14 years

Answer 2

let Sunil's age be x yrs
then,Anu's age=(x+4)yrs

eight years ago,
Sunil's age=(x-8)yrs
Anu's age=[(x+4)-8]yrs =(x-4) yrs

according to question,3(x-4)=x-8
=> 3x-12=x-8
=> 3x-x=-8+12
=> 2x=4
=>x=4/2
=> x=2

Sunil's age=(x+4) yrs=(10+4) yrs=14yrs
