2.The sum of two nos is "S" and their quotient is "P/Q" .The Numbers are
a. ps/q, qs/q
b. s/p, s/q
d.ps/p+q , qs/p+q
Let us say X & Y are the two numbers. It is given that X+Y=S (Eqn 1) and X/Y = P/Q (Eqn 2).
From eqn1, Y=S-X; Substituting for the value of Y in equn 2, you should get X/(S-X) = P/Q .
Solving this you should get X=PS/(P+Q) & Y= QS/(P+Q), which is answer choice (D). Hope this helps.
