Answer / sumit jha

when ws peter as as paul is nw?? (x-y) years ago!!

so those years ago paul's age= y-(x-y) yrs

now qstn says peter is twice the age as paul ws then.

so x/2 = y-(x-y)

or x/2=2y-x

or x= 4y - 2x

or 3x = 4y

or y = 3/4x

rplacing d value of y in d equation x+y=35 we get answer as

-----
x=20
-----
y =15.
------

thus (x-y)=5 yrs ago y was 10 and x is twice that=20.
but x+y=35

Answer / paul

The answer is 21 years old (age of Peter).

Equation:

let x = present age of Peter
y = present age of Paul

When Peter has the same age as Paul (y yrs. old), age of
Paul is y/2 yrs. old. Since the differences of there ages
are equal for the 2 events, we have the equation...

x - y = y - y/2
y = (2/3)x

Substituting the equation of y to the equation x + y = 35,
will give us....

x + (2/3)x = 35

therefore, x = 21 (age of Peter)

Imagine you are standing in front of a mirror, facing it. Raise your left hand. Raise your right hand. Look at your reflection. When you raise your left hand your reflection raises what appears to be his right hand. But when you tilt your head up, your reflection does too, and does not appear to tilt his/her head down. Why is it that the mirror appears to reverse left and right, but not up and down?
