Question

sudha is twice as old as garima. 10 years ago, sudha was three times as oldas garima. find sudha's present age.

Answer 1

Heya!
---------


Let present age of Garima be x years

Then present age of Sudha will be 2x years

Ages 10 years Ago,
--------------------------


3( x - 10 ) = ( 2x - 10 )

=> 3x - 30 = 2x - 10

=> x = 20


⭐Age of Garima = 20 years

⭐Age of Sudha = 40 years


-----------------------------------------------------------------------------------------------------

Answer 2

let the present age of garima is x ⇒ sudha's present age is 2x

10 years ago the age of garima is x - 10

10 years ago the age of sudha is 2x - 10

but given that 10 years ago sudha was three times as old as garima

⇒ (2x - 10) = 3(x - 10)

⇒ 2x - 10 = 3x - 30

⇒ x = 20

present age of sudha is 2x

⇒ present age of sudha is 2 × 20 = 40 years
