You can put this solution on YOUR website! ANSWER::::
i. P+Q=2(P-Q), P*Q=675
P+Q=2P-2Q
"3Q=P" EQUATION CONNECTING THEIR AGES
ii.BUT WE ARE GIVEN P*Q=675, THEN INPUT P=3Q INTO P*Q=675 =>3Q^2=675 SOLVE FOR Q AND GET Q=15, FROM 3Q=P THEN 3*15=P=45
THEREFORE, THE EQUATION CONNECTING THEIR AGES (MAN AND HIS SON) IS (P=3Q) AND THEIR AGES ARE 45 AND 15 YEARS RESPECTIVELY.
