LET ONE EVEN NUMBER BE 2X,ITS NEXT NUMBER WILL BE 2X+2
THEIR RECIPROCALS ARE 1/2X AND 1/2(X+1)
THE SUM OF RECIPROCALS IS 1/2X+1/2(X+1)=5/12
TAKING LCM
(X+1+X)/2(X)(X+1)=5/12
(2X+1)/2X(X+1)=5/12
CROSS MULTIPLYING
12(2X+1)=2*5X(X+1)
24X+12=10X^2+10X
10X^2-14X-12=0
5X^2-7X-6=0
5X^2-10X+3X-6=0
5X(X-2)+3(X-2)=0
(X-2)(5X+3)=0
SO X-2=0
OR X=2
SO THE 2 NUMBERS ARE 2X=4 AND 2X+2=6
