Answer 1

.
$\bold { Let \: present \: age \: of \: hema \: be \: \: x \: years}$


After 15 years, her age will be ( x + 15 ) years




Given in question that after 15 years she will 4 times of her present age


Hence,

x + 15 = 4x

=> 15 = 4x - x

=> 15 = 3x

=> 3 × 5 = 3 × x

$\text{ Hence, \: Present \: age \: of \: Hema \: is \: \: 5 \: years }$

Answer 2

Answer:

5 years

Step-by-step explanation:

Let the present age of Hema be x years

After 15 years , her age will be ( x + 15 )

In the question, after 15 years she will 4 times of her present age = 4x

By the sum

= x + 15 = 4x

= 15 = 4x - x

= 15 = 3x

= 15/3 = x

= 5 = x

The present age of Hema is 5 years
