Question
Average of four numbers is 16. Sum of smallest and
largest number is 45. If difference between other two numbers is 1, then find the square of second smaller number.Solution
Let four numbers in increasing order is a, b, c and d. => a + b + c + d = 4 x 16 = 64 => a + d = 45 => b + c = 19 According to question, => c – b = 1 => b = 9, c = 10 => b² = 81
