The average of five numbers, given in a particular order, is 32. The average of the first three numbers is 28, while that of the last three numbers is 34. What is the average of the first two numbers?

29

Sum of 5 numbers are = 5 × 32 = 160

Sum of first three numbers = 3 × 28 = 84

Sum of last three numbers = 3 × 34 = 102

Let middle number = N

So , 102 + 84 - N = 160

N = 26

Let average of first 2 number = x

So , Sum of first 2 number = 2x

84 = 2x + 26

x = 29

So , Average of first two number is 29.
