Question

kashyap is 21 year old and kinshuk is 15 year younger to kashyap.After how many years will kashyap be twice as old as kinshuk.

Answer 1

Age of Kashyap = 21 yrs

Age of Kinshuk = 21 - 15 = 6 years

Let the age of Kashyap be twice as old as kinshuk after x years.

(21 + x) = 2(6 + x)

21 + x = 12 + 2x

21 - 12 = x

x = 9

Hence, after 9 years Kashyap will be twice as old as Kinshuk.

Answer 2

twice of kashyap: 30
kashyap age:21
30-21=9
so, after 9 years kashyap age will be twice of kinshuk
