(a)6
(b)8
(c)9
(d)Data inadequate
(e)None of these
Answer
Explanation
$5 P 7+8 Q 9+R 32=1928 \Rightarrow(500+10 P+7)+(800+10 Q$ $+9)+(100 R+30+2)=1928$ $$\begin{aligned} & \Rightarrow 10 P+10 Q+100 R+1348=1928 \\ & \Rightarrow 10(P+Q+10 R)=580 \\ & \Rightarrow P+Q+10 R=58 \Rightarrow R=5 \text { and } \end{aligned}$$ ⇒ Maximum value of $Q$ is 9 [for $P=9$ in second case]
