At the present, Palash is three times Arnav's age. After 7 yr, Palash will be twice Arnav's age, then how many times will Palash's age be in another 14 yr time with respect to Arnav's age then?

Let Arnav's age = k yr
Then, Palash's age = 3k yr
Acoording to the question, 3k + 7 = 2(k + 7)
⇒ 3k + 7 = 2k + 14
⇒ k = 7
∴ Age of Arnav after 14 yr = 7 + 14 = 21 yr
and Palash's present age = 21 yr
Hence, Palash's age is one time of Arnav's age .
