Question

Father’s age is three times the sum of ages of his two children . After 5 years

his age will be twice the sum of age of two children. Find the age of father . ?​

Answer 1

Answer:

Let age of 2children be =X and Y

Father's age 3(x+y)

Age of children after 5years =x+5+y+5= x+y+10

Age of father = 2(x+y+10)=3(x+y)+5

2x+2y+20=3x+3y+5

2x-3x+2y-3y+20-5

-x-y+15 ×(-)

X+y-15=0

x+y=15

Wkt,3(x+y)=3(15)=45

Answer 2

Answer:

45

Step-by-step explanation:

let the fathers age be A

let the age of children be X and Y

given,

A=3(X+Y).......1

A+5=2(X+Y+10)........2

FROM 1

3(X+Y)+5=2(X+Y+10)

X+Y=15

A=45
