Answer 1

Answer:

$\sf{The \ age \ of \ younger \ person \ is \ 20 \ years.}$

Given:

• Two two student in a batch of age ratio 2 : 3.

• The sum of their age is 50.

To find:

• The age of younger person.

Solution:

$\sf{Let \ constant \ be \ n.}$

$\sf{According \ to \ the \ first \ condition.}$

$\sf{\leadsto{Age \ of \ elder \ person=3n}}$

$\sf{\leadsto{Age \ of \ younger \ person=2n}}$

$\sf{According \ to \ the \ second \ condition.}$

$\sf{2n+3n=50}$

$\sf{\therefore{5n=50}}$

$\sf{\therefore{n=\dfrac{50}{5}}}$

$\sf{\therefore{n=10}}$

$\sf{\longmapsto{Age \ of \ younger \ person=2\times10}}$

$\sf{\longmapsto{Age \ of \ younger \ person=20 \ years}}$

$\sf\purple{\tt{\therefore{The \ age \ of \ younger \ person \ is \ 20 \ years.}}}$

Answer 2

Answer:

In my own opinion,

The answer is =20

Step-by-step explanation:

1st: The sum of ratios is 2+3=5

    and the sum of their ages are 50

   therefore, the younger person's age is

    2/5×50/1

    =100/5

     therefore, the answer is 20.

     I hope it's helpfull.
