Question

The sum of the present age of mother and her daughter is 50 years after 20 years mother's age will be twice her daughter's age at the time find the present age

Answer 1

Answer:

mother age= 40 year and doughter age=10 year

Step-by-step explanation:

let, doughter and mother present age will be x and y

a/c to question,

X+y=50------(1)

and,. 2*(x+20)=(y+20)

2x-y=-20-------(2)

solving eqn 1 and 2

X=10 year and y=40 year

Answer 2

let mother's age be x and daughter's age be y

x+y = 50

x+20 = 2(y+20)

x-2y = 20

by elimination method

(x+y=50)×2

=2x+2y=100

x - 2y = 20

3x = 120

x = 40

y = 50-x

y = 50-40

y = 10
