Question

Ellie is now four times as old as her son. in 5 years time she will be three times as her son. how old is Ellie son now?

Answer 1

Let her son be x

Ellie is 4x

In 5 years time:

Her son = x + 5

Ellie = 4x + 5

Given that she will then be 3 times as old as her son:

4x + 5 = 3(x + 5)

Solve x:

4x + 5 = 3(x + 5)

4x + 5 = 3x + 15

x = 10

Answer: Her son is 10 years old.

Answer 2

$\bold {\huge {Solutions:-}}$


Let age of Ellie's son be x
Ellie age = 4x

After 5 years

Ellie's son age = x + 5
Ellie age = 4x + 5


A/q


=> 4x + 5 = 3(x + 5)

=> 4x + 5 = 3x + 15

=> x = 10

Hence,

$\bold {\underline {Ellie's~son~is~10~years~old}}$
