Question

. Fifteen years from now Ravi's age will be four times his present age. What is Ravi's
present age?
​

Answer 1

Answer:

Present age of Ravi is 5 years.

Step-by-step explanation:

Let,

Present age of Ravi be years.

So,

= > Age of Ravi after 15 years = present age of Ravi + 15 years

= > Age of Ravi after 15 years = a years + 15 years

= > Age of Ravi after 15 years = ( a + 15 ) years

According to the question :

= > Age of Ravi after 15 years = 4 times of his present age

= > ( a + 15 ) years = 4 times of a years

= > a + 15 = 4a

= > 15 = 4a - a

= > 15 = 3a

= > 15 / 3 = a

= > 5 = a

Hence ,

Present age of Ravi is 5 years.

$\bold{Let \: the \: ravi \: present \: age \: be \: x}$

$\bold{so \: his \: age \: after \: 15 \:year \: be \: x + 15}$

$\bold{\underline{According \: to \: question}}$⤵️

$= > x + 15 = 4x \\ = > 4x - x = 15 \\ = > x(4 - 1) = 15 \\ = > x(3) = 15 \\ = > x = \frac{15}{3} \\ = > x = 5$

➡️$so \: the \: ravi \: present \: age \: = x = \bold{5 \: years}$
