Answer 1

Answer:

Now FATHERS AGE IS 60 YEARS

Step-by-step explanation:

man has two daughters and one son

let their ages x,y,and z say

father's age F say

by given data,:

x+y+z=F. .......... (1)

In 15 years their age will be as ...

(x+15)+(y+15)+(z+15)=1 1/2(F+15)

• (* ***1 1/2=3/2)

x+y+z+45=3/2(F+15)

x+y+z=(3/2F)+(45/2)-45.........(2)

equation (1) &(2) are equal...

so..

F=(3/2)F-45/2

F(1-3/2)=-45/2

F(-1/2)=-45/2

F=45

fathers age =45 years...

AFTER 15 YEARS...

FATHERS AGE=45+15

=60years
