Question

lalithas age is 3 times her son's age. ten years ago she was 5 times her son's age. find their present age.​

Answer 1

Answer:

$\large\boxed{\sf{60\:yrs, \: 20\:yrs.}}$

Step-by-step explanation:

Let, present age of Lalitha = 3x yrs.

Therefore, present age of her son = x yrs.

10 years ago

Age of Lalitha = (3x-10) yrs.

Age of her son = (x-10) yrs.

According to Question,

$= > 5(x - 10) = 3x - 10 \\ \\ = > 5x - 50 = 3x - 10 \\ \\ = > 5x - 3x = 50 - 10 \\ \\ = > 2x = 40 \\ \\ = > x = \frac{40}{2} = 20$

Hence, Present ages of Lalitha and her son are 60 yrs. and 20 yrs. respectively.
