0 votes 0 votes Possible values of P,Q are (1,64), (2,32), (4,16), (8,8) Possible values of P+Q are 65, 34, 20, 16 35 is not possible. Hence, option D would be the answer mudit23june answered Jun 27, 2017 mudit23june 346 points comment Share See all 0 reply Please log in or register to add a comment.
0 votes 0 votes Factor of $64$ are: $1,2,4,8,16,32,64$. It is given that $P\times Q=64$. The number of pairs of $(P\times Q)=64$ are: Options $(P\times Q)=64$ $P+Q$ A $16\times 4=64$ $20$ B $64\times 1=64$ $65$ C $8\times 8=64$ $16$ D $32\times 2=64$ $34$ So from above Option (D) is not possible.
