Explanation:
Answer:
5 year
Step-by-step explanation:
Let the present of Hema be 'a' year.
After 15 years:
Her age = present age + 15 year
Her age = a + 15 year
In question, after 15 year she will be 4 times of her present age:
= > age after 15 year = 4*present age
= > a + 15 = 4a
= > 15 = 4a - a
= > 15 = 3a
= > 15/3 = a
= > 5 = a
Hence,
Her present age = a = 5 year
