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
