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
[tex]x+6=3(x-7)[/tex]
[tex]\implies x+6=3x-21[/tex]
[tex]\implies 2x=27[/tex]
[tex]\implies x=\frac{27}{2}=13.5[/tex] years
Age of Karishma after 10 years = 13.5 + 10 = 23.5 years
Hope this answer is helpful.
