Question

fifteen years from now ravi's age wil be 4 times his present age what is ravi's present age

Answer 1

Let present age of Ravi be X years.



After 15 years age of Ravi = ( X + 15 ) years.




According to the question,




X + 15 = 4X



4X - X = 15


3X = 15

X = 5 years

Present age of Ravi = X = 5 years

ʟᴇᴛ ʀᴀᴠɪ's ᴘʀᴇsᴇɴᴛ ᴀɢᴇ = x

ʀᴀᴠɪ's ᴀɢᴇ ᴀғᴛᴇʀ ғɪғᴛᴇᴇɴ ʏᴇᴀʀs = x + 15

$= > x + 15 = 4x \\ \\ = > 15 = 4x - x \\ \\ = > 15 = 3x \\ \\ = > \frac{15}{3} = x \\ \\ = > 5 = x$

ʜᴇɴᴄᴇ, ʀᴀᴠɪ's ᴘʀᴇsᴇɴᴛ ᴀɢᴇ = x = 5 ʏᴇᴀʀs !
