The average of six numbers is S and the average of three of these is T.If the average of the remaining three is U, then
Choose the correct choice from the following options
A) S= T + U	B) 2S= T + U	C) S= 2T + 2U	D) None of these	E) Cannot ne determined
Explanation :   Clearly, we have S =(3T+3U/6)   or 2S= T + U   Answer : 2S= T + U
<result>B</result>
