Answer 2

The age of Karishma after 10 years is 23.5 years

Step-by-step explanation:

Given:

Age of Karishma after 6 years is 3 times her age 7 years ago

To find out:

Age of Karishma after 10 years

Solution:

Let the present age of Karishma is x years

Age of Karishma 7 years ago = x - 7

Age of Karishma after 6 years = x + 6

According to the question

$x+6=3(x-7)$

$\implies x+6=3x-21$

$\implies 2x=27$

$\implies x=\frac{27}{2}=13.5$ years

Age of Karishma after 10 years = 13.5 + 10 = 23.5 years

Hope this answer is helpful.
