Answer 1

let the age of shreya be 3x
age of kavita be 4x
after five years there age ratio be 3x+5/4x+5=4/5
=5(3x+5)=4(4x+5)
=15x+25=16x+20
=25-20=16x-15x
=5=x
=x=5 age of sherya=3x5=15years
age of kavita=4x5=20years

Answer 2

Heya..
Here is your answer ----

Let age of Shreya be 3x
And, Let age of Kavita be 4x

Ac/q

=> (3x + 5) / (4x + 5) = 4 / 5

=> 5 (3x + 5) = 4 (4x+5)

=> 15x + 25 = 16x + 20

=> 15x - 16x = 20 - 25

=> -x = -5

=> x = 5

Age of Shreya = 3x = 15 years
Age of Kavita = 4x = 20 years

HOPE IT HELPS....!!!!
