Explanation:
✬ Murali's Age = 15 Years ✬
✬ Mozhi's Age = 20 Years ✬
Step-by-step explanation:
Given:
Mozhi's age is 5 years more than that of Murali's age.
Five years ago ratio of their ages was 3:2.
To Find:
What are their present ages ?
Solution: Let present age of Murali be x years. Therefore,
➟ Present age of Mozhi = (x + 5) years
Five years ago their ages were
Murali's age = (x – 5) years
Mozhi's age = (x + 5 – 5) years
Ratio of their ages = 3 : 2
⟹ x/x – 5 = 3/2
⟹ 2 × x = 3(x – 5)
⟹ 2x = 3x – 15
⟹ 15 = 3x – 2x
⟹ 15 = x
So , present age of Murali is 15 years and
➮ Present age of Mozhi is 15 + 5 years
➮ 20 years.
