Answer 1

Answer:

Shobha's age = 10 years and her mother's age = 40 years.

Explanation:

Given that,

Shobha's mother is 4 times Shobha's age.

If we assume shobha's age as x years.

Then, Shobha's mother's age will be 4x years.

Now, 5 years later age of,

• Shobha = (x + 5) years
• Her mother = (4x + 5) years.

According to the question,

Shobha's mother is now 3 times Shobha's age.

⇒ (4x + 5) = 3(x + 5)

⇒ 4x + 5 = 3x + 15

⇒ 4x - 3x = 15 - 5

⇒ x = 10

Hence, Shobha's age is 10 years.

And also, her mother's age is 4x = 40 years.
