Q. What could be the maximum value of Q in the following equation?
5P9 + 3R7 + 2Q8 = 1114

• sol:
  (1) (2)
  5 P 9
  3 R 7
  2 Q 8 +
  ———-
  11 1 4
  ———-
  =>2+P+Q+R=11
  so at max Q, P=R=0,
  therefore Q=11-2=9.

• q to be maximum p and r should be minimum.i.e 0 ,0.hence 509+307+2Q8=1114 ,Q=9
• 10 years agoHelpfull: Yes(17) No(1)
• here p + Q + R =9.(.but P !=Q!=R)(!= means not equal.)
  => max(Q/p/r) =8..because (8+1+0=9)

• how do you get 2+p+q+r=11,how means
  5 p 9
  3 R 7
  2 Q 8
  (1)(2)
  --------
  11 1 4
  9+7+8=24 so below the for P+Q+R+2=11
  and 5+3+2=10 so we have to add 1 for 10 then we will get sum as 11

• 2+P+Q+R=11
  P+Q+R=9
  P=0
  R=0
  Q=9

• @ ANBARASAN A
  in ten's digit we have p,q and r.
  after adding the one's digit of all the three numbers we get 24.
  that means carry is 2.
  so p+q+r+2=11 or p+q+r=9
  so q will be max when both p and r are min.
  now if we take p and r are equal then put p=r=0 then q will be 9
  and if we take p!=r then take one of them as 0 and another as 1 then q will be 8

• p+r+q=9
  ...max value of q might be 9

• Can anyone explain the solution precisely??
• 10 years agoHelpfull: Yes(0) No(0)
• let p=q=0;
  maxvalue=p+q+r=9
  so. max value of q= 9

• 5 P 9
  3 R 7
  2 Q 8 +
  ———-
  11 1 4
  ———-
  =>2+P+Q+R=21
  so at max Q, such that P+R=10,
  therefore Q=9

• how do you get 2+p+q+r=11
• 10 years agoHelpfull: Yes(0) No(0)
• for me its 9..
  range of Q can be bw (0 to 9)
  so for max value if Q is 9...then(5P9+3R7)=1114-298=816(where in addition 9+7=16,1 carry..so P+R+1=1(considering P=0,R=0),and 5+3=8)....
• 10 years agoHelpfull: Yes(0) No(0)
• 2+p+r+q=11.....so q can be max 9
• 10 years agoHelpfull: Yes(0) No(0)
• ok Q=9.......
  then 11-2 how it will came here
  Q=11-2=9
• 10 years agoHelpfull: Yes(0) No(0)
• we can assume p=0 and R=1........
  then 509+317+2Q8=1114.
  2Q8=288.
  then Q=8 is answer
