mrs goel is 27 years older than her daughter rekha. after 8 years she will be twice as rekha. find their present ages?
let rekha's present age be x
therefore, mrs goel's present age is x+27
after 8 yrs...
rekha's age=x+8
mrs goel's age=x+27+8
according to the problem....
2(x+8)=x+27+8
2x+16=x+35
2x-x=35-16
x=19
rekha's present age=x=19yrs
therefore mrs goel's present age=x+27=(19+27)yrs=46yrs
