Question

Seema is now 9 years older than Beena in 10 years seema will be twice as old as Bina was 10 years ago find their present ages

Answer 1

Let the present age of beena =x
and present age of seema= x+9

In 10 years(After 10 years)
seema's age= (x+9)+10= (x+19)

10 years ago(Before 10 years)
beena's age= x-10


Given,
seema's age after 10 years= 2( beena's age before 10 years)
=> x+19 = 2(x-10)
=> x+19 = 2x-20
=> x= 39


•°• Present age of Beena x= 39
and present age of seema x+9= 48.

Answer 2

Answer:

Step-by-step explanation:

Let the present age of Seema be =(X +9)years

Let the present age of Bina be= X years

After 10 yrs,

Age of Seema={(X+9)+10} yrs

Before 10 yrs,

Age of Beena=(X-10) yrs

Therefore age of Seema after 10 yrs= 2(X-10) yrs

A.T.Q

X+19=2(X-10)

X+19=2X-20

X-2X=-19-20

X=39 yrs

Therefore present age of Seema is = 39+9= 48 yrs

Present age of Beena=39 yrs
