Question

After 10 years age of Chandra sahithi willBe half of her mother five year ago find age of her mother after five years will be 20 more than three times of present age of sahithi .Find the present ages of sahithi and her mother

Answer 1

Answer:

Step-by-step explanation:

Let the age of Chandra be x

the age of her mother be y

According to first condition,

(x+10)=1/2 (y-5)

2(x+10)=y-5

2x-5=-25-----------------------(1)

According to the second condition,

y+5=3x+20

-3x+y=15-------------------(2)

therefore,

y=15+3x

Substituting the value of y in equation (1),

2x-(15+3x)=-25

2x-15-3x=-25

-x=-10

X=10

Substituting the value of x

y=15+3x

=15+3 (10)

=15+30

=45

Ans: Chandra's age is 10 yrs

Her mother's age is 45 yrs.
