Set S contains exactly 10 numbers and has an average (arithmetic mean) of 6.2. If one of the numbers in Set S is increased by 6, while all other numbers remain the same, what is the new average of Set S?	Choose the most appropriate option:
A) 6.6  B) 6.7  C) 6.8  D) 6.85  E) 6.9
Old set S - Total is avg * no of elements = 6.2*10= 
<gadget id="calculator">6.2*10</gadget>
<output>62</output>
62   If one number is increased by 6 then total increased to  62+6= 
<gadget id="calculator"> 62+6</gadget>
<output>68</output>
68   New avg - 68/10= 6.8.   Hence answer is 6.8.
