Answer 2

Answer:

Sharan is 15 years old

Step-by-step explanation:

Let the ages of Kiran , Arjun, Sharan are  $a$ $b$ and $c$ respectively

Given that Kiran is 4 years older than Arjun who is 5 years older than Sharan

 Now convert above sentence in mathematical data

  Kiran is 4 years older than Arjun ⇒ Kiran age a =b+4 (b is Arjun age)

  Arjun is 5 years older than Sharan ⇒ Arun age b = c+5 ( c is Sharan age)

 Total ages of three members  $a+ b+c = 59$

   add (a= b+ 4)  ⇒  b+ 4+ b+ c =59

                               2b + c= 59 -4 = 2b + c= 55

   add ( b= c+ 5) ⇒  2 (c+5 ) +c=55    

                              2c + 10 +c =55

                              3c + 10 = 55

                               3c = 45

                                  c = 15

 Sharan age = 15
