The digit in the unit’s place of a number is equal to the digit in the ten’s place of half of that number and the digit in the ten’s place of that number is less than the digit in unit’s place of half of the number by 1. If the sum of the digits of number is 7, then what is the number	Choose the most appropriate option
A) 34	B) 49	C) 162	D) 52	E) 79
Let the ten’s digit be x and unit’s digit be y   Then, (10x+y)/2=10y+(x+1)   8x-19y=2   And x+y=7   X=5 and y=2   Then reqired number is 52   Option 52
