i) Present age of Lakshmi is x+24 years.

ii) Present age of Priya and Lakshmi 6 years ago are x-6 years and either x+18\ or\ 3x-18 years respectively.

iii) Present age of Priya is 18 years and present age of Lakshmi is 42 years.

Step-by-step explanation:

(i)

Given:

Present age of Priya is 'x'.

Lakshmi is 24 years than Priya. Therefore, we need to add 24 to present age of Priya. So,

Lakshmi's present is equal to x+24 years.

(ii)

6 years ago means we need to subtract 6 from their present ages.

Therefore, the age of Priya 6 years ago is equal to x-6 years.

Lakshmi's age 6 years ago = Present age - 6 = x+24-6=x+18

Also, as per question, 6 years ago, Lakshmi's age is thrice of Priya which is equal to 3(x-6)=3x-18

Therefore, Lakshmi's age 6 years ago is either x+18\ or\ 3x-18 years.

(iii)

As per question, Lakshmi's age 6 years ago is thrice that of Priya's age 6 years ago. Therefore,

x+18=3(x-6)\\x+18=3x-18\\3x-x=18+18\\2x=36\\x=\frac{36}{2}=18

Therefore, present age of Priya is 18 years.

Present age of Lakshmi is 24 more than that of Priya. So, 24 + 18 = 42 years.
