Question

The age of a mother is two times the age of her daughter, after five year the sum of their ages will be 49 years, The age of daughter of two year will he:??????????​

Answer 1

Answer:

Let the age of mother &daughters be x,y respectively

x=2y —————A

after 5 years mothers age =x+5

after 5 years daughter’s age =y+5

sum of their age =x+5+y+5 =x+y+10

x+y+10 =49 {given} —————B

put x=2y in B

2y+y+10 = 49

3y =39

y=13; put y=13 in A x=2y =2*13 =26

check mothers age 26 daughters age =13; ratio 26/13 =2 Tallies

5years later 26+5= 31yrs is mother daughter 13 +5 =18

sum of ages =31 +18 =49 =as given in the problem above Tallies

Answer :After 5 years The age of Daughter will be 18 years

Answer 2

Let that daughter age is = x

And mother's age is = 2 x

After two years

$(x+2) + (2x+2) = 49 \\3x+4 = 49 \\ </h2><p>3x = 45 \\ x= 15$

After two year mother's age will be

2x+2

2× 15+2
