Question

Yasmeen's mother is four times as old as Yasmeen.After 5 years, her mother will be three times as old as she will be then. Find their present ages.​.​

Answer 1

Step-by-step explanation:

Yasmin's mother's age= 4x

Yasmin's age= x

After 5 years,

Yasmin's mother age= 4x +5

Yasmin's age = x +5

Therefore,

4x+5=3(x+5)

4x = 3x +15 -5

4x-3x=10

x= 10

Yasmin's age =10

Yasmin's mother's age= 40

Answer 2

Answer:

LET YASMEEN PRESENT AGE BE X

SO HER MOTHER AGE IS 4X

AFTER 5 YEARS

YASMEEN WILL BECOME X + 5

AND HER MOTHER WILL BE 4X + 5

SO 4X + 5 = 3( X + 5 )

4X+5 = 3X + 15

X = 10

YASMEEN AGE IS X = 10 YEARS

HER MOTHER'S AGE IS 4X = 10 × 4 = 40 YEARS
