In a 2 digit no unit's place is halved and tens place is doubled. diff bet the nos is 37.digit in unit's place is 2 more than tens place. Select the correct option:
A) 36	B) 46	C) 56	D) 66	E) 76
let tenth place digit be x &amp; unit place be y   then no. is = 10x + y   if unit place is halved and tens place is doubled   then no. is = 10*2x + y/2   10*2x + y/2 -(10x+y)=37   =&gt; 10x - y/2 = 37 .....(1)   and, y-x=2 ....(2)   solving, x=4,y=6   no. is 46   ANSWER:46
