Question

sum of age of mother and her daughter is 60 years after 15 years mothers age will be twice as that of her daughter's age at that time find their present age

Answer 1

X
$x + 15 = 2{y + 15} \\ x + y = 60$

Answer 2

Answer:

Step-by-step explanation:

Let age of mother be a and age of daughter be B

Therefore age of mother=60-b

Age of daughter=60-a

Age after 15 yrs=

(60-b)+15=2(60-a)

60-(60-a)+15=2(60-a)

60-60+a+15=120-2a

a+2a=120-15

3a=105

a=35

Now present age of mother

=60-b=60-(60-a)

=60-(60-35)

60-25=35yrs

Present age of daughter=60-a=60-35=25yrs
