Question

Roy is 11 year old and his uncle is 59 year old. How many years ago was Roy’s uncle 7 times as old as Roy?

Answer 1

before 3 years Roy's uncle was 7times as old as Roy
because
present age of Roy's uncle=59
before 3 years=59-3=56
present age of Roy=11
before 3 years=11-3=8
so,if we multiply 8×7
we get 56
we got Roy's uncle age
we had multiplied 7 because they said that Roy's uncle was 7times of Roy's age
so
before 3years Roy's uncle age was 7times as old as Roy.

Answer 2

=(11-x)/(59-x)=1/7
=7(11-x)=59-x
=77-7x=59-x
=77-59=-x+7x
=18=6x
=18/6=x
=3=x Answer!!!
