9
=> Let the age of Arjun be 5x
Sahadev be 7x
=> Then , Arjun is 9 year older , let Arjun age be 5x +9
=> Sahadev is 9 year younger , let Sahadev age be 7x - 9
According to question ,
=> 5x + 9 = (7x - 9) 2
=> 5x + 9 = 14x - 18
=> 5x - 14x = -18 - 9
=> -9x = -27
=> 9x = 27
=> x = 27/9
=> x = 3
Arjun = 5x = 5 × 3 = 15 year
Sahadev = 7x = 7 × 3 = 21 year
Sahadev be 7x
=> Then , Arjun is 9 year older , let Arjun age be 5x +9
