You can put this solution on YOUR website!
let the average age of 8 men be 8m%2F8
if the average is decreased by 2 years when two of them replaced by two young boys b
%286m%2B2b%29%2F8
if two of those who are replaced are 22 and 28 old, then we have
%28%286m+%2B+22+%2B+28%29+%2F+8%29-+2+=+%286m+%2B+2b%29+%2F+8
%28%286m+%2B+50%29+%2F+8%29-+2+=+%286m+%2B+2b%29+%2F+8
%28%286m+%2B+50%29+%2F+8%29-++%286m+%2B+2b%29+%2F+8=2
%28%286m+%2B+50%29+-++%286m+%2B+2b%29%29+%2F+8=2
%286m+%2B+50+-++6m+-+2b%29+=2%2A8
+50+-+2b+=16
+50+-+16+=2b
34+=2b-> age of two young boys
then average age of two boys is
34%2F2=17
