A set of consecutive positive integers beginning with 1 is written on the blackboard. A student came along and erased one number. The average of the remaining numbers is 35*7/17. What was the number erased?	Choose the correct choice from the following answers:
A) 7
B) 8
C) 6
D) 5
E) 4
Explanation :   Let the higher number be n and x be the number erased.   Then((n(n+1)/2)+x)/(n+1) = 35*7/17 = 602/17   Hence, n = 69 and x =7 satisfy the above conditions.   7nswer : 7
