Question
In a game of 100 points, if P gets 100 points, Q gets
10 less than P and R gets 30 less than P. Then, how many points can R get if Q gets 180 points?Solution
P:Q = 100:90, P:R = 100:70 Q/R = (Q/PĂ P/R)Â = 90/100Ă100/70Â = Â 90/70 = 9:7 â´ In a game if Q gets 180 points Q/R= Â 9/7 = (9 Ă 20)/(7 Ă 20)=180/140Â R gets 140 pointsÂ
