Question

Anu is four years older than sunil. Eight years ago ,Anu was three times sunil's age. Find the ages of Sunil and Anu​

Answer 1

Answer:

Anu is four year older than sunil

If sunil's age = x

anu's age = x+4

Anu was 3 times sunil's age 8 yeas ago

(x+4) - 8 = 3(x-8)

⇒ x - 4 = 3x - 24

⇒ x - 3x = -24 + 4

⇒ -2x = -20

⇒ x = -20/-2 = 10

Sunil's age = 10years

Anu's age = 10+4 = 14years

Answer 2

Step-by-step explanation:

let sunil age be x

So, Anu age is y

A.T.Q

y=x+4 (¡)eq...

y-8=3(x+4)

y=3x+4+8

y=3x+12 (¡¡)eq...

After subtracting equation (¡) from(¡¡)

y=3x+12

y= x+ 4

(-) (-) (-)

_______

0=2x+8

0=2x+8

2x=8

x=4

y=x+4

y=4+4

y=8

therefore, age of Anu is 8 years and age of Sunnil is 4 years.
