Meena is three times as old as Leena . after 5 years , she will be as twice as age of Leena , find there present ages​

Answer»

Answer :-

Let present age of meena = X years

Let present age of meena's MOTHER =Y years

After five years age of meena =(x + 5) years

After five years age of meen's mother =(Y +5) years

According to question

y = 4x -  -  - (1)

y   + 5 = 3(x + 5) -  -  - (<klux>2</klux>)

Put (1) in (2) , we get

4x + 5 = 3x + 15

4x - 3x = 15 - 5

x = 10

y = <klux>40</klux>

Meena's present age =10 years

Meena's mother's present age =40 years
