Answer 2

Question:-

• After 15 years, Hema's age will become four times that of her present age. Find her present age.

To Find:-

• Find the present age of Hema.

Solution:-

• Let Hema's present age be x years.

According to the Question:-

$\sf\longrightarrow \: x + 15 = 4x$

$\sf\longrightarrow \: 15 = 4x - x$

$\sf\longrightarrow \: 3x = 15$

$\sf\longrightarrow \: x = \cancel\dfrac { 15 } { 3 }$

$\sf\longrightarrow \: x = 5$

Hence ,

• Present age of Hema is 5 years.
