There are four numbers a, b, c, d. If the sum of all possible distinct
Right Answer is: B
Total possible groups = (a, b), (b, c), (c, d), (a, c), (a, d), (b, d)
As per question a+b+b+c+c+d+a+c+a+d+b+d = 14916
3(a + b + c + d) = 14916
(a + b + c + d) = 4972
Hence average = Sum of numbers/ No. of numbers = 4972/4 = 1243.
