Present age of Sarita is 5 times the age of his son.

• Let the present age of his son be x years then present age of Sarita is 5x

5 years ago :

• Sarita's age was 25 times the age of her son.
• Her sons age was x - 5
• her age = 25(x - 5)

›› 25(x - 5) = 5x - 5

›› 25x - 125 = 5x - 5

›› 25x - 5x = 125 - 5

›› 20x = 120

›› x = 120/20

›› x = 6

So,

Present age of Sarita is 5x = 5× 6 = 30years

Answer 2

Sølution :

• Let the age of her son be x

• Then age of Sarita is 5x

★ Now , 5 YEARS AGO :

• Age of her son = x - 5

• Age of Sarita = 25( x-5 )

☯ According To The Question :

=> 25( x-5 ) = 5x - 5

=> 25x - 125 = 5x - 5

=> 25x - 5x = - 5 + 125

=> 20x = 120

=> x = $\sf \dfrac{120}{24}$

=> x = 6

• Age of her son = 6 years

• Age of Sarita = 6 × 5 = 30 years
