Question

vivek is 5 years elder to kishor . The sum of reciprocal of their ages is 1/6 . Find their present ages​

Answer 1

Let the present age of Kishor be x years. Vivek is older than Kishor by 5 years. So, Vivek's age will be x + 5. But age cannot be negative so, age of Kishore is 10 years and that of Vivek is 10 + 5 = 15 years.
